Description Ryan Dotts 2018-10-07 20:36:49 UTC 
Application: kwin_x11 (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.15.0-36-generic x86_64
Distribution: KDE neon User Edition 5.13

-- Information about the crash:
- What I was doing when the application crashed:
Booting to desktop
- Custom settings of the application:
Default settings for KWin (recent reformat) that come with KDE Neon 5.13 (neon-useredition-20181004-1723-amd64.iso).  The only related item installed is the latest nvidia binary drivers (390.48) for the GTX 670M.

Initially the desktop appeared to have not booted at all, but switching to tty2 and back restored it.  No unusual behavior since.  This has happened consistantly on several startups.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

kwin_x11 (5.14.1) using Qt 5.11.2

- What I was doing when the application crashed:

Had just resumed from standby and logged in.  The little bug icon was already in the system tray when the lock screen was cleared.  Using proprietary Nvidia drivers.

kwin_x11 (5.12.6) using Qt 5.9.5

- What I was doing when the application crashed:
resuming from suspension to ram (stand-by)
- Unusual behavior I noticed:
alpha layer becomes noisy (windows using opengl or desktop icons with didascaly), i think this is caused by nvidia driver miscommunication
- Custom settings of the application:
nvidia driver 390.77

New crash information added by DrKonqi

kwin_x11 (5.14.4) using Qt 5.11.2

- What I was doing when the application crashed:

Just resumed from sleep.  Oddly, it only happens when I am using any window decoration theme OTHER than Breeze.  When I use Breeze, this crash doesn't happen, and the icon captions do not get corrupted as they do with the others.

Comment 22 Frederik Gladhorn 2019-08-12 07:02:15 UTC 
I would guess this is an alignment issue, see the Intel Intrinsics Guide:
https://software.intel.com/sites/landingpage/IntrinsicsGuide/#text=load_si128&expand=5191,3063,5661,3343
Load 128-bits of integer data from memory into dst using a non-temporal memory hint. mem_addr must be aligned on a 16-byte boundary or a general-protection exception may be generated.

In other words: we should check the alignment of dstP as far as I can tell.
Comment 23 Frederik Gladhorn 2019-08-13 07:14:12 UTC 
I guess my previous comment can be discarded, looking at the backtraces, the pointers seem to be aligned, this is puzzling. I cannot reproduce it.

Comment 25 Vlad Zahorodnii 2019-08-27 05:33:09 UTC 
@Frederik My guess is that we don't reset GLVertexBuffer::streamingBuffer() on a graphics reset.

Comment 27 David Edmundson 2019-08-28 11:35:36 UTC 
I did some more graphics reset patches in Qt and I think our handling is wrong.

The reset flag is set on until you call makeCurrent a second time, then it's cleared.

We have a tonne of places, especially screen change handling code, that calls makeCurrent without a graphics reset check. My theory is that if we get in here, we could have a reset that we don't handle.

I'll flood my kwin with qDebug and see if I can trigger that happening.

Sorry, seems like I am stupid enough. Looks like this time I caught the crash, didn't I?

That's perfect, thanks.

What's important above is the line we don't see in this output:

qCWarning(LIBKWINGLUTILS) << "GL error: context lost";
Comment 45 Gennadiy 2019-10-24 17:03:48 UTC 
Maybe I haven't got some debug packages? I have had libkwinglutils11-dbgsym and some more qt5 dbgsym packages, but should I have something special?

After last Update KDE Neon 5.17.2
the folders and files names on desktop now looks fine (not strange colors and pixels)
the kwin keep crashing and restarting after reactive from suspend, but the names now are better.

Comment 54 Vlad Zahorodnii 2019-12-15 13:36:44 UTC 
Alright, the streaming vertex buffer should be okay after a graphics reset since the GlxBackend destroys it, which leaves with another option - perhaps kwin attempts to render something before it has a chance to process the Scene::resetCompositing signal. I have ordered an NVIDIA video card, so hopefully I'll be able to investigate this problem more thoroughly soon.
Comment 55 Vlad Zahorodnii 2020-01-08 00:00:11 UTC 
So, I've been running nvidia for quite a while and haven't managed to reproduce the crash yet. Each time a graphics reset occurs, KWin recovers from it successfully. :(

I'm not sure whether I should be happy or sad about it.

[scenes/opengl] Remove outdated hack to reset vertex buffers

Summary:
Scene opengl has a callback for when we have a GL error. One of the
handlers for an error calls scheduleVboReInit the history shows it was a
forerunner to the GLX_NV_robustness_video_memory_purge but resetting
only one tiny part based on debug output.

When we get here we schedule a reset of the vertex buffer, via a timer.
When the timer is caled we have no idea what GL context was last
current, if it's not the currect context then the main scene
GLVertexBuffer will be deleted but not correctly re-initialised.

We have two very common crashes with a corrupted
GLVertexBuffer::streamingBuffer() which would match up perfectly.

Given that we now have a proper mechanism to reset the entire scene, we
don't need this timer based hack and resolve that problem.

Note, I could not reproduce this crash and this fix is based on a strong theory. 

If we get a duplicate with Plasma 5.18beta or newer, please reopen.

kwin_x11 (5.19.4) using Qt 5.14.2

- What I was doing when the application crashed:The laptop  had suspended and upon relogin, the Kwin crashed, Chrome and other software had render issues too.

No reports from a Plasma version newer than 5.20. I think we consider it to have been fixed in 5.21 or a newer version.
