Description Vassilis Virvilis 2022-11-02 12:38:17 UTC

Really really sorry for this but no backtrace.

Kwin is getting killed by X with (2 last lines)
The X11 connection broke: I/O error (code 1)
X connection to :0 broken (explicit kill or server shutdown).

I trust that I dind't kill my kwin on purpose. Can any keyboard combination do this?
This time it took 2-3 days to be killed like this. Here are all the messages that it spits in these 3 days. I really hope that you will be able to find something valuable.

I mentioned this bug in https://bugs.kde.org/show_bug.cgi?id=461052 (which is another bug)

After the kwin crash I have a 50% change for a plasmashell crash. This is of course is another bug but it is entirely possible that the plasmashell crash comes first and lead to the kwin death mentioned here. I can't tell because when kwin is killed the desktop is unresponsive.

One other observation. Some times kwin is killed (cannot be found with ps - no titlebars in the windows) and sometimes it hangs (unresponsive desktop, titlebars in windows and can be found by ps).

Next time (in 2 - 3 days) I will try to attach a strace.

Qt Version: 5.15.6
Kernel Version: 6.0.0-2-amd64 (64-bit)
Graphics Platform: X11
Processors: 4 × Intel® Core™ i5-3570K CPU @ 3.40GHz
Memory: 31.3 GiB of RAM
Graphics Processor: Mesa Intel® HD Graphics 4000
Manufacturer: Gigabyte Technology Co., Ltd.

Comment 2 Grzegorz 2022-11-03 11:59:26 UTC

I have the same problem

Comment 3 Vassilis Virvilis 2022-11-03 12:43:22 UTC

ok it did it again. Same error but different message. kwin got killed so no backtrace.

The X11 connection broke: I/O error (code 1)
XIO:  fatal IO error 0 (Success) on X server ":0"

Here is the combined output in the console from kwin and plasmashell.

I don't want to spam this bug so I won't post any more of these outputs unless somebody finds them useful.

Comment 4 jed-bugs.kde.org 2022-11-04 07:38:33 UTC

This has been happening to me as well. Today, it got so bad that kwin was crashing every few minutes. Interestingly, things stablized after I killed and restarted plasmashell.

Comment 5 Vassilis Virvilis 2022-11-05 05:52:31 UTC

It did it a again this on (remote with xpra) unlock time with error code 22.
I am posting only a few lines of intermixed output (plasmashell & kwin) just in case somebody may spot something.

Comment 6 Vassilis Virvilis 2022-11-05 05:58:26 UTC

So far the X errors are:

1. Local: The X11 connection broke: I/O error (code 1) X connection to :0 broken (explicit kill or server shutdown). --> kwin killed
2. Local: The X11 connection broke: I/O error (code 1) XIO:  fatal IO error 0 (Success) on X server ":0" --> kwin killed
3. Remote:  The X11 connection broke: I/O error (code 1) XIO:  fatal IO error 22 (Invalid argument) on X server ":0" after 6963214 requests (6963214 known processed) with 0 events remaining. --> kwin killed

I will keep updating the list.

Note: It looks like the hung case is much rarer. Maybe it happens when the plasmashell is busted and it is actually a different bug. When kwin dies user input are dying too so I can't be really sure that plasmashell is actually alive before I restart kwin.

Maybe all 3 above are different bugs. I certainly hope that this isn't the case though because it looks terribly difficult to diagnose this without a backtrace let alone 3 of them.

Comment 7 Daniel Schulte 2022-11-05 22:14:03 UTC

I also have encountered this (quite a lot) in the last days (since I updated to 5.26.x). Sometimes I need to `kwin_x11 --replace` multiple times a day - sometimes I also then need to `pkill plasmashell && kstart5 plasmashell` as it becomes non-responsive.

Messages I've seen so far:
The X11 connection broke: I/O error (code 1) X connection to :0 broken (explicit kill or server shutdown)
The X11 connection broke: I/O error (code 1) XIO:  fatal IO error 22 (Invalid argument) on X server ":0" after 171015 requests (171015 known processed) with 0 events remaining.
The X11 connection broke: I/O error (code 1) XIO:  fatal IO error 2 (No such file or directory) on X server ":0" after 78026 requests (78026 known processed) with 0 events remaining.

There are more which I don't have anything saved for as they are from re-running kwin_x11 from a terminal.
There isn't anything interesting in dmesg or Xorg.0.log.

Comment 8 Vassilis Virvilis 2022-11-08 13:37:21 UTC

I also got the 'error 2: No such file or directory' error:

The X11 connection broke: I/O error (code 1)
XIO:  fatal IO error 2 (No such file or directory) on X server ":0"
      after 5589828 requests (5589828 known processed) with 0 events remaining.

kwin killed so no strace.

Comment 9 Vassilis Virvilis 2022-11-10 08:03:43 UTC

In my home. I upgraded to 5.26.3 (debian unstable) and was hit again by this . Not sure which error code though, because it was the first kwin instance and not one that I run from terminal so I didn't have stderr output.

Hello, I'm facing this problem too.
If I understand the problem might be resolved by reverting commit 768238fdc06eed3dce36da3baf811cb70db42b5c, is that correct? Or the two last comments state something different? Thanks!

7682 is bad, not sure if it's the same about 151a

Ok, I'm testing now Mesa 22.2.3 with 7682 reverted.
In my case the problem happens seldomly usually upon the creation of a notification box which is rendered black and it may take some days before I may say that the issue is fixed.

Comment 19 xxmlud 2022-11-10 21:44:15 UTC

Hi, this same thing happens to me, Kwin dies randomly, what I do to get back to normal I run alt+f2 and type "systemctl restart display-manager".

I have a bug created, but this one seems more extensive. My graphics card is an Intel

Comment 21 Vassilis Virvilis 2022-11-11 07:53:54 UTC

Aa a reproducer. Thanks for that.

I will try it at home and report back.

I hope that you are onto something. If memory serves  a lot of the crashes are related with virtual dekstop switches - not sure if that is a Knotification though...

We 'll see. Much appreciated anyway...

Comment 22 Vassilis Virvilis 2022-11-11 09:43:04 UTC

This is probably another bug. I looked around but can't anything. Probable bad keywords. (no keyboard input)

This time my desktop hanged. (Not sure if I had mouse pointer). Certainly not keyboard. Windows decorations were there.

I switch to console and back to X. Now I have mouse pointer but no click. No keyboard.

Now I can't Ctrl-Alt-F2. I ssh and do sudo chvt 2

I restart kwin from console (DISPLAY=:0 kwin --replace)

Now I have mouse pointer + click but still no keyboard.

I restarted plasmashell. Kate crashed as per: https://bugs.kde.org/show_bug.cgi?id=461318

Still no keyboard input.

*** Do you happen to know what process I need to restart to gain keyboard again?. I had to reboot. and I lost a lot of state.

In the meantime as I promised I straced both kwin and plasmashell. Everything looks ok. They are waiting for input:

kwin:
futex(0x56164c8eaec4, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 0, NULL, FUTEX_BITSET_MATCH_ANY

plasmashell:
futex(0x55796b5c3f14, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 0, NULL, FUTEX_BITSET_MATCH_ANY

This bug is more severe and more difficult / rare to trigger. If somebody has a pointer for this bug  I will post there. Otherwise I will open a new bug later today.

Unfortunately, if it is, it makes difficult to bisect the original one.

Dunno, sorry. Just making tests to figure out what happens and why

Comment 26 Vassilis Virvilis 2022-11-14 13:43:19 UTC

Thanks for looking so hard at this. Much appreciated.

Yesterday I had another instance of this (or another bug). This time kwin wasn't killed (windows have their titles) but kwin was unresponsive. However I had keyboard and I was able to run 'kwin --replace' and then everything got ok.

I don't remember how I got to the terminal though. Either I was already there (konsole had focus) or Alt-Tab worked which strikes me as somewhat weird.

Unfortunately no logs for this new one.

I am not sure I am helping anyone with these awfully incomplete reports. I will try my best to run the reproducer. Maybe I would be able to report something more useful.

Older version would spam notifications so hard it could have killed any version of Mesa

One question, do you have two monitors?

No. I have one monitor per machine. But I have work and home computer. Some times I use xpra to access the work machine.

Sometimes I got a local crash. Sometimes I got a remote crash. Sometimes I have keyboard other I have mouse. Sometimes the keyboard input is borked like a modifier (like Ctrl or Alt) is pressed. The borked modifier is probably a remote thing only but I am not 100% sure. It's all over the place really.

Seriously though. If I try to open thousands or million of files I wouldn't expect a crash in libc or in the kernel. I would expect an error "out of resources" but then I guess my program would crash because I wouldn't have been checking for errors. Is something like that goes on here?

Comment 31 xxmlud 2022-11-14 22:09:04 UTC

I do work with two monitors, and I wanted to find some relation.
 When kwin breaks and I have the Konsole in focus I restart the service "display-manager", otherwise I connect with alt+f2. The truth is that the logs are not enlightening. I am lost with this issue

I suspect something happens with rendering process

Comment 33 Daniel Schulte 2022-11-15 10:03:35 UTC

Not sure how much of this is just a coincidence or if it is actually related:
Before I had the "KWin just quits" issue I had problems where KWin sometimes just "forgot to update a window", meaning a window starts flickering between some old window states instead of rendering new ones. The issue was "fixable" by toggling compositing off and on again (using Ctrl+Shift+F12 by default I think). I had that issue for a few years but never really investigated as just pressing the keys was an easy work around for me. How often this happened varied from once every few days to multiple times an hour, though subjectively it was occurring more often lately than a year ago.

At the beginning of November I changed my default browser from Chrome to Firefox and that issue didn't happen anymore for a few days so I thought maybe it was a wired interaction between Chrome and KWin. Then this issue started happening.

What both issues/behaviors have in common is that I noticed that usually there are notifications being shown when it happens. The "old issue" with stuck rendering showed the notifications just fine and also still updated a small (maybe 30 px?) region around the notification popup. With this issue I saw a notification pop up appear as a black rectangle and then KWin crashing (and sometimes also Plasmashell hanging after the KWin restart).

Comment 34 Silvan Calarco 2022-11-15 10:48:40 UTC

I also used to have the problems reported by Daniel but in my case it seems they stopped happening since Qt update to 5.15.7 (with KDE patches applied to qtbase and qtdeclarative modules).
Currently I didn't have any issues at all in the last 5 days on two computers (with Intel and AMD/ATI chipsets) where they happened once every 1-2 days. I also run many times Oleg's reproducer without any issue. It may just be a coincidence, BTW I also updated Mesa to 22.2.3 and KDE Plasma to 5.26.3, are you all using such releases?

All the same, except Qt release (5.15.6)

I'm running these version except that all the Qt Packages have the KDE patches, as that is what ArchLinux ships at the moment.

For me the v3 reproducer works. I'm, thinking of putting a check in there to see if KWin is still alive before sending the next notification and quit if not. Maybe it's somewhat consistent how many notifications it takes for KWin to crash.

Comment 37 xxmlud 2022-11-16 06:13:02 UTC

Hello,

These are the versions that I use.

KDE Plasma: 5.26.3
KDE Frameworks: 5.99.0
QT Version: 5.15.7

Is there any way to put kwin_x11 in debug mode? I have seen that in Wayland it is possible, but in X11 I have not found anything.

Comment 38 Vlad Zahorodnii 2022-11-16 09:56:11 UTC

Do you know what tends to cause

kwin_core: XCB error: 152 (BadDamage), sequence: 48054, resource id: 69786721, major code: 143 (DAMAGE), minor code: 3 (Subtract)

e.g. did you close some window?

Comment 39 Vlad Zahorodnii 2022-11-16 10:00:17 UTC

It looks like https://invent.kde.org/plasma/kwin/-/commit/7eca5f44dbc2b094468e7430f784ff1e7f372989 was not backported to 5.26. I backported it just now, hopefully it's going to reduce the amount of BadDamage errors.

Hello,

In my case, the "crash" comes after a notification comes up.

Could it be related to some bug in "(org.kde.plasma.notifications)"?
Can you check if it appears in the same situation?

For the moment I have disabled notifications in the application that gives me more notifications on the screen.

No, it is a Mesa bug, which has been bisected and tested with reproducer (see attachments)

Comment 44 xxmlud 2022-11-17 20:23:10 UTC

I will report next Tuesday if I had any new crashes.

Retry with hardware acceleration disabled.
It crashes after updating Mesa 22.1 -> 22.2 branch

Comment 46 kde-bugs-io-drsf32 2022-11-19 17:56:05 UTC

I keep having this for weeks now and can confirm the last line before X goes down always is the BadDamage one.
I think it started like 6-8 weeks ago. Once it starts to happen, restarting kwin_x11 mostly won't help for any longer period of time. In the best cases it lasts long enough to allow for a controlled Desktop shutdown, package update and reboot - sometimes not even that. After reboot it keeps going for another 24 to 48 hours before kwin crashes start again. I 

I don't think notifications are the one culprit. Yes, notifications sometimes seem to trigger the problem (notably causing latte dock to hang until killed), but not always. Sometimes a mere desktop switch apparently is enough to get it down again. In the worst cases just coming back to the x11 VT (remapping the desktop) did end it. I'll keep re-starting and updating until it gets better since I get it there is a promising patch now. But the general instability really is getting to me :-) 
If you want logs of anything you don't already have, drop me a line.
Thanks for looking into this.

Comment 47 xxmlud 2022-11-21 16:57:02 UTC

Hi, kde-bugs-io-drsf32@spamfilter.de. Is there any way we users can help?

I have disabled notifications for several days and have not had any crashes.

Comment 48 Vlad Zahorodnii 2022-11-23 11:42:19 UTC

I can reproduce the issue with the attached test app. Thank you, Oleg, for providing it and also bisecting mesa. :)

kwin 5.26 didn't have any significant X11 changes besides one fix to prevent frozen windows due to xcb_generate_id() returning a bad id, however this bug is reproducible even after reverting those changes, so I think that we can rule out kwin.

One peculiar thing about this bug is that if compositing is disabled, reproducer v3 can "hang" xorg. That's it, at some point, notification windows will stop popping up and other X11 connections will hang in general. Restarting plasmashell helps to fix that.

kwin gets killed when it repaints the screen, specifically binds the window texture

so if plasmashell manages to "break" xorg, it sort of explains why kwin_x11 gets killed

I built mesa 22.1.7 and the issue is not reproducible there. I didn't bisect mesa changes, but the ones mentioned in https://gitlab.freedesktop.org/mesa/mesa/-/issues/7674 look like good candidates.

It looks like glXMakeCurrent(Display, Window, GLXContext) got broken in Mesa 22.2. It's worth noting that Qt uses glXMakeCurrent(Display, Window, GLXContext) rather than glXMakeCurrent(Display, GLXWindow, GLXContext). I made a quick and dirty patch to test that theory https://invent.kde.org/-/snippets/2423. I ran reproducer v3 a couple of times, the bug doesn't seem to occur.

Regardless, glXMakeCurrent(Display, Window, GLXContext) is still a valid case and it must work.

Comment 50 CapsAdmin 2022-11-23 18:00:27 UTC

So it might be finally solved?

I made a duplicate issue, but having read the comments here I can add that it seems/feels to happen when:

- launching an application that creates an opengl context or something that triggers the desktop turning off the compositor (for example me developing an opengl application)
- screen lock due to inactivity. (not sure if happens on lock out or logging back in though)
- abnormally high gpu usage (ie running something very gpu intensive by mistake when programming)

The URL @ the top of the ticket points to [this](https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/19972) issue which is part of the `22.3` release which looks to be _almost_ ready to ship.

Comment 55 Vassilis Virvilis 2022-11-30 21:45:50 UTC

Out of curiosity,

I have no experience with opengl/mesa so the question may be invalid.

The main culprit that is being reversed is a patch that was adjusting reference counting of ... something (opengl context? not sure).

The question is: Are we sure that the patch being reversed is buggy? We know for sure that it caused a regression and kwin crashes. However, isn't it possible that this is a failure of Qt/KDE/Plasma/kwin to handle the new "correct" behavior that the patch introduced?

Don't get me wrong I am thrilled and grateful that you guys found it and have the mesa guys reverting it but I am just curious...

Anything to do with resource management is tricky :)

I'm sure that the Mesa folks wouldn't have reverted it unless they thought
it looked like an issue on their end.
