Description mlchatnoir666 2022-10-17 14:36:58 UTC

SUMMARY

At a random point, sometimes when I’m not even using my computer actively, the whole system taskbar/notification/menu freezes and doesn’t answer to interraction anymore.
When the “freeze” happens, I can still use normally the already-opened applications (can only switch between them with alt+tab though). The taskbar is simply unrespeonsive, and moving windows makes the whole display crash even further (then only my mouse can move and not interract with anything).

It’s a very frustrating bug because even the terminal shows all-black when I try to open it after a crash, so I can’t really do anything besides a forced manual restart.
The one time I managed to have a terminal open before the freeze, the following commands worked to “fix” it:
```killall plasmashell
kstart plasmashell```
Which convinced me this is a Plasma bug and not something else.

STEPS TO REPRODUCE

The bug seems to occur randomly

SOFTWARE/OS VERSIONS

Operating System: EndeavourOS
KDE Plasma Version: 5.26.0
KDE Frameworks Version: 5.99.0
Qt Version: 5.15.6
Kernel Version: 6.0.2-arch1-1 (64-bit)
Graphics Platform: X11
Processors: 12 × AMD Ryzen 5 5600X 6-Core Processor
Memory: 31.3 Gio of RAM
Graphics Processor: AMD Radeon RX 6600 XT
Manufacturer: TOP ACHAT
Product Name: CUSTOM
System Version: V1

ADDITIONAL INFORMATION

I filed this bug under kwin but I have really no idea if it's this specific product causing problems. Also, if needed, I can probably run commands in a terminal next time the freeze happens, don't hesitate to ask me specific commands.

Thanks for the help/reaction

Might be related to https://bugs.kde.org/show_bug.cgi?id=460513

Comment 2 Nicolas Fella 2022-10-17 15:11:49 UTC

Is it crashing or freezing?

If it's crashing we need a backtrace. Please follow https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl to get a backtrace for plasmashell and post that here

Comment 3 mlchatnoir666 2022-10-17 15:16:51 UTC

(In reply to Nicolas Fella from comment #2)
> Is it crashing or freezing?

I'm not sure which one it is (it's either freezing indefinitely, or crashing).
When running coredumpctl, the last line is from before I updated to 5.62.0 and started having crashes. Should I try another method or does it mean I don't have logs for this?

Comment 4 Nicolas Fella 2022-10-17 16:44:08 UTC

If the background gets black and the panel disappears then Plasma crashed. If the panel stays but is unresponsive it's froze. That seems to be the case here

Please while it's frozen run "gdb --pid $(pidof plasmashell)", then type "bt", hit enter and paste the result here

Thanks!

I got another freeze, had to restart my computer again because I couldn't do anything, but it froze as soon as I launched it and I managed to run the command. It kinda looks like there's no error in these logs, I'll try again if I get another freeze to see if it changes

Comment 6 mlchatnoir666 2022-10-18 15:58:01 UTC

I'm having another big freeze right now, taskbar unusable, notification all-black. Here's the trace of the plasmashell processus:

Hope this helps, because these freezes are making it hard to use my computer

Comment 7 mlchatnoir666 2022-10-18 16:26:04 UTC

If this helps, I also tried "gdb --pid $(pidof kwin_x11)" and it made my whole computer freeze

Comment 8 mlchatnoir666 2022-10-19 12:35:06 UTC

updated yesterday to plasma 5.26.1 but the freeze still occurs.
the bt command gives the exact same result as the one posted 2 messages above

Comment 9 mlchatnoir666 2022-10-19 12:53:33 UTC

Okay I have more interesting logs from journalctl /usr/bin/plasmashell
I had a crash happen at precisely 14:32 (my taskbar is frozen on this time since) so here are the logs for the prior 5 minutes. Hopefully this is enough.

Comment 10 mlchatnoir666 2022-10-19 13:02:51 UTC

there is no prior occurence of either
qt.qpa.xcb: QXcbConnection: XCB error: 2 (BadValue), 
or
qt.qpa.xcb: QXcbConnection: XCB error: 136 (Unknown),

before those logs, so it's likely where the problem stands

Comment 11 mlchatnoir666 2022-10-24 14:17:51 UTC

does anyone know how to fix this? It's making my computer unusable and super hard to rollback....

Comment 12 Timothy B 2022-10-31 02:56:24 UTC

I'm experiencing similar behavior at least once every day, but I was able to continue using my session after I switched to a TTY and killed kwin_x11 from there. Plasmashell and all other apps running on the desktop session, especially Firefox, continued to work once I returned from the TTY. However, it's usually triggered when I use the Alt+Tab switcher and notice it being completely black before freezing completely. This started after I upgraded my system to Frameworks 5.99 and before upgrading Plasma to 5.26. Since I updated the kernel at the same time as Frameworks, I'll have to test my system with the 5.15 LTS kernel to see if it's also reproducible there.

Operating System: Manjaro Linux
KDE Plasma Version: 5.26.2 (and also on 5.25.5)

Comment 13 Timothy B 2022-11-01 16:15:18 UTC

The screen just froze on me again a few minutes ago, this time running the 5.15.75 kernel. Again, switching to a TTY and killing kwin_x11 made the session usuable again. At the time of the freeze, I was using Firefox as usual, and the only logs I got were the same XCB errors as in comment #10:

The kwin_scripting warnings shown above have also appeared in the journal logs every few minutes as I continue to use the system.

Quite interestingly, I set a custom global shortcut to kill and restart KWin (Ctrl+Alt+Shift+K) a few days ago, and that shortcut didn't work at all while the screen froze.

Comment 14 hockeymikey 2022-11-01 18:33:48 UTC

I have been having this issue pop up about daily now locking up my system and needing to restart it. Everything is frozen besides existing open windows. 
https://bugs.kde.org/show_bug.cgi?id=460594#c9
Highlights what I am seeing in logs perfectly. It seems is freezes exactly when I get a notification (sometimes, it's very rare and odd when I do). 
I'm using an Omen 15 with a 4800H and a 2060 Nvidia GPU if that helps. 
I am running Arch and am completely updated on that end. I do have Firefox open (as well as Waterfox classic) when it happens, but I'm not able to narrow any down since I'm usually pretty busy multitasking. It does not happen when switching tasks, I can just step away from my computer and come back to plasma frozen. It will be frozen on the time and second of the following logs exactly like in comment 9 that I linked.

Comment 15 mlchatnoir666 2022-11-01 23:33:19 UTC

UPDATE: it seems like my crashes come from notifications as stated by hockeymikey, and for my case it's probably telegram (no crash since I turned off telegram's notifications). I suspect their custom emojis being the cause of this, but I'll need to investigate further, and I still can't tell whether the bug comes from QT/KDE not handling things or telegram dispatching unprocessable notifications.

@hockeymickey since you seem to have the same bug as me, do you think you can guess which app causes them?

Comment 16 Timothy B 2022-11-02 14:22:57 UTC

Created attachment 153401 [details]
Journal logs and stack trace

The random screen freeze just happened yet again right after invoking the Alt-Tab switcher. This time, I changed the switcher style to Compact, and I was able to generate a stack trace and core dump from the TTY with `pkill -ILL kwin_x11`. Quite interestingly the journal logs showed that my KWin restart global shortcut (Ctrl+Alt+Shift+K) is working, but apparently KWin didn't respond to SIGTERM while it froze. However, plasmashell did respond to my other global shortcut (Ctrl+Alt+Shift+Backspace) and restarted in the background, but the wallpaper became black after KWin restarted, so I had to restart it again with the same shortcut.

The command for the KWin restart shortcut is currently `nohup sh -c "systemctl --user restart plasma-kwin_x11.service"`, but I will need to change that to make it kill KWin instead of terminating.

Comment 18 hockeymikey 2022-11-02 14:44:06 UTC

(In reply to mlchatnoir666 from comment #15)
If I would have to guess (they are black so can't be sure), it's kde connect and a notification from my phone, which is snapchat probably. Or it could be teams or thunderbird. I don't think the emojis are causing issue or anything custom, but maybe it is. If it was must be some edge case.

Comment 19 mlchatnoir666 2022-11-02 15:43:45 UTC

(In reply to hockeymikey from comment #18)
at least it shows it's not limited to one app, so likely a problem coming from KDE and not a specific app dispatching wrongly formatted notifications

Comment 20 Timothy B 2022-11-05 01:13:38 UTC

It looks like my issue has already been reported in bug #457847, and I wasn't aware of that ticket's existence when I started getting those random screen freezes. Apologies in advance for polluting this bug ticket, and any updates regarding my issue will now appear in the linked bug ticket.

I also see this on 5.26.3 (debian unstable). It's laptop with Intel GPU (i7-10610U). 

It also happens mostly when notification is displayed.

plasmashell_and_kwin_x11_thread-apply-bt.txt

I notice also such a hang. I left today at 12:05 the system.
When I came back at 13:45 the time was stuck at 12:15, and three notifications from kdeconnect where still visible.
To me it looks like this hang is likely to happen if kdeconnect is producing multiple notifications fast in a row.
I assume this is the case when I changed WLAN accesspoints in this time and my phone is connecting to the new acesspoint.

I gathered core dumps of kwin_x11 and plasmashell.
Attached is a `thread apply all bt`, but there are many threads in each and am not sure which one is supposed to do something.
Most of them are waiting for something, but I cannot say for what.
If wanted, I can add more debug symbols.

Thread 1 in each process seem to be middle in some processing, plasmashell waiting for some mutex, kwin_x11 for some xcb request.

Tried to look a little further in plasmashell process.
It looks like thread 1 is inside some QSGThreadedRenderLoop and is waiting to be woken by some other thread:

Kinda, I'm using an 2021 Omen 15 with an AMD 4800H and a Nvidia 2060m. So I think the Radeon graphics is used for the built in display, but my external ones are ran through the Nvidia gpu. Hope that helped, I appreciate all your help.

Nope, I'm on an Intel system, *but* I mostly experience kwin_x11 crashes (it actuallt dies without Dr. Konqui showing up and I have to start it via konsole/yakuake/krunner, whichever I can access at that moment) and only a few plasmashell freezes in between.

I did notice that when kwin dies repeatedly, if I restart plasmashell it won't die again, at least for the rest of the day.

Also, the crashes/freezes seem pretty random: sometimes while receiveing a notification or several, sometimes when I Shift+Del an emal in kmail (confirmation popup) and some other times kwin just dies without an obviuos (to me) trigger.

From the responses so far I don't see any concrete explanation why Plasma would cause this. This and similar problems reported by other people make me suspect there might be something wrong with X11/Graphics drivers, but I can't really prove it

Indeed, I initially thought this was a kwin_x11 problem. Only after seeing these reports of Plasma freezing I noticed those.

Not sure, they mention having black rectangles. In my case I can see the content of all the windows, in fact I see all windows from all desktops, but no black rectangles.

I've been trying to isolate the cause but so far no luck. Sometimes it happens when I get a notification, other times it happens when I switch windows with alt+tab and once it happened just by using the open file dialog (which shows a pop-up with the possible file names).

Comment 35 Sergio 2022-11-25 09:27:00 UTC

Experiencing the same issue on Manjaro (see https://forum.manjaro.org/t/plasmashell-freezes/127677/2).

Good news is that it is easy to check whether the issue is a freeze in plasmashell or another issue. Furthermore if the problem is a freeze in plasmashell it can be worked around without any data loss.

1. switch to a virtual console (e.g. CTRL+ALT+F2), login there, kill plasmashell (e.g. killall plasmashell);
2. go back to the graphics console (e.g. CTRL+ALT+F1), if the panel is now gone, then the problem was plasmashell *freezing*.
3. now it should be possible to get the runner (ALT+F2), restart plasmashell from there (e.g. plasmashell --replace).

The above procedure lets all your applications survive.

I am seeing the issue with X11 (on an Intel Haswell laptop with integrated Intel graphics), so this is definitely not a Wayland-related or Wayland specific problem.

If I understand correctly, plasmashell uses a *cooperative* multitasking model for its widgets, so it is enough to have one widget freezing to get a complete plasmashell freeze, which makes freezes like this somehow easy to see, particularly if a non-official widget is used.

The model has the advantage of being very lightweight, but clearly has some disadvantage. Is there any possibility to complement it with a watchdog, so that when the shell freezes after some time it is automatically restarted and one can get an indication of the last widget the execution thread was in at the freeze time?

Comment 36 Dāvis 2022-12-15 01:15:19 UTC

I have been experiencing exactly this same deadlock. I'm using Arch Linux with AMD Radeon Vega Mobile 8 GPU. It happens kinda rarely but still annoying.

And it's definitely related with notifications (it freezes right after displaying some) but I don't remember which one in particular it was, maybe Discord. Also I might be remembering wrong but maybe when notification shows up and you mouseover somewhere it.

For `plasmashell`

So basically for both it seems to be stuck in

That never comes.

Comment 37 JC 2022-12-15 01:51:53 UTC

I updated my system to kde-frameworks v5.101.0 and kde-plasma (including kwin) v5.26.4. After 4 days, my system seems to be operating normally again.
