Comment 1 Thomas Lübking 2013-12-06 18:24:21 UTC

Driver bug, see eg. (amarok) bug #323635

Please try OpenGL 1.3 and attach the ouptut of

    qdbus org.kde.kwin /KWin supportInfo

(if OpenGL 1.3 works)

or

   glxinfo

(if not)

so we can see what GPU/driver this is, thanks.

Does it happen with GL 2 and GL 3 or only one of them?
Does it happen with "kwin_gles --replace&"?
I assume it does not happen with a stable MESA version?

It happens with GL 1.2, 2.0 and 3.1
It did happen with MESA 9.2 also, but I didn't dig into it, because I could live with xrender.
I only upgraded to 10.1 because the xf86-video-intel V 2.99.xxx crashes when kscreen detects an external monitor and the vertical resolution is smaller than my laptop screen and by switching to V 3.00.xxx kscreen works flawless. Now, with 10.1 and xrender on, some (but not all) window titles have bitmap errors, so I tried to reenable GL.
I noticed one more thing: kwin either crashes always or works all the time when I do a reboot. Right now it works, so I can't try kwin_gles at this time.

(In reply to comment #4)

Ok???
Can you then also provide a crashtrace for GL 1.2?

> Now, with 10.1 and xrender on, some (but not all) window titles have bitmap
What deco / graphicssystem? Try changing the graphicssystem ("kcmshell4 kwincompositing", 3rd tab)

> I noticed one more thing: kwin either crashes always or works all the time

Try entering runlevel 3, unloading intel modules, reloading them (modprobe) and back to runlevel 5 instead of a reboot (which is likely faster, though ;-)

New crash information added by DrKonqi

kwin (4.11.3) on KDE Platform 4.11.3 using Qt 4.8.5

- What I was doing when the application crashed:
Enabled compositing using OpenGL 3.1
Crashes using all OpenGL versions, yet I believe it worked a couple days ago, before updating, these could be related:
xf86-video-intel to 2.99.906
xorg-x11-server to 7.6_1.14.99.905 (from .904)
xorg-x11-driver-video to 1.0.10

- Custom settings of the application:
Enabled Effects:
Blur
Dashboard
FadeHighlight Window
Kscreen
Login
Logout
Magic Lamp
Maximize
Minimize animation
Screen edge
Screenshot
Sliding popups
Taskbar Thumbnails
Translucency
Wobbly windows
Startup feedback
Dialog parent
Desktop Cube (+Animation)
Desktop grid
Flip Switch

Comment 7 Thomas Lübking 2013-12-31 00:56:36 UTC

Since it's also with the beta drivers, the crash will likely be related to the updates, yes.

For the moment, do not try to use GL 3.1 - the chip/driver combo (check glxinfo) does (likely) not support it (but OGL3.0 - at best) and trying to create a core profile for 3.1 gets the driver into some invalid state[1] - this might persist across processes.

-> Set compositing to eg. xrender or disable it, reboot, try to re-enable compositing, but select OpenGL 2, *not* 3.1 at any time.

[1] see bug #327310 - might be a "dupe"

Comment 8 Alexander Patrakov 2014-04-13 13:54:20 UTC

I understand that the bug is RESOLVED UPSTREAM, however there is no upstream report yet, and there is some additional information for those who still hit it on Haswell hardware.

Additional information: The bug exists if kwin uses the system Qt engine, and selecting the Raster engine together with OpenGL 3.1 is a viable workaround.

So - is it really a bug in the i965 Mesa driver? Or maybe just a clash of rendering contexts due to Qt? In other words - which upstream should the bug be reported to?

Comment 9 Thomas Lübking 2014-04-13 14:04:35 UTC

Though QGLPaintEngine2 can hit the same crash, the "native" graphicssystem does not use a GL context - you do mean it does only happen with this, but not with the raster graphicssystem?

And since changing the graphicssystem implies a restart, are you sure the Qt graphicssystem is relevant and not just coincidental?

What's the ouput of "glxinfo" (please attach)?
(I don't think the chip/driver combo already supports OGL 3.1 yet? Haswell is not i965)

Comment 10 Alexander Patrakov 2014-04-13 14:26:50 UTC

I did restart kwin during the test: kwin --replace

As for the relevance of the graphicssystem, I have to retract my statement. Now it works with 3.1 and Native (tested by logout and relogin), but changes in this area do have a chance to crash kwin on the next login or on restart, or to cure the crash.

glxinfo on haswell

As you requested, I am adding glxinfo output to the bug.

Comment 12 Thomas Lübking 2014-04-13 14:36:43 UTC

Thanks, Haswell, not i965 (though iirc. same driver lib)
However, GL 3.1 is not yet supported by the driver so this will likely be bug #327310 (esp. if only GL 3.1 is affected) - we lack confirmation since the OP suggests differently but has not provided a crashtrace for esp. GL 1.2.

Comment 13 Alexander Patrakov 2014-04-13 14:43:44 UTC

The bug does manifest itself with GL 2.0, too. I have not tried 1.2, as it doesn't offer color correction, but will try now. Just let me rebuild kwin once again with -g3 -ggdb debug symbols :)

Comment 14 Alexander Patrakov 2014-04-13 14:55:55 UTC

Comment 15 Alexander Patrakov 2014-04-13 14:59:12 UTC

Switched to 1.2 and Raster, logout, login => no crash, transparency works.

Comment 16 Alexander Patrakov 2014-04-13 15:01:02 UTC

Comment 18 Alexander Patrakov 2014-04-13 15:04:15 UTC

Forgot to say that these crashes appeared only after logout and relogin, not immediately after applying the setting.

Comment 20 Alexander Patrakov 2014-04-13 15:07:56 UTC

Reenabled effects, logged out, logged in => no crash, effects work.

Comment 21 Alexander Patrakov 2014-04-13 15:10:10 UTC

Changed to 3.1 and system, logged out, logged in => no crash. Will not test anymore to avoid spamming you.

Comment 22 Alexander Patrakov 2014-04-13 15:19:41 UTC

Sorry, I have just realized that I have put -g3 -ggdb to CFLAGS only, but not to CXXFLAGS. Here is a better backtrace for you, with GL 1.2 and Raster:

This is with OpenGL 2.0 and Raster.

This was a Xorg bug, fixed by http://cgit.freedesktop.org/xorg/xserver/commit/?h=server-1.15-branch&id=eec04d76a39a7334de4e00ef9f0f6e44c92b3d91

Many thanks for your efforts and esp. the provided valgrind log.

Ooc, do you get 
a) an opengl 3.1 context (check "qdbus org.kde.kwin /KWin supportInformation") and
b) reasonable perfomance on that?

qdbus report

The performance is reasonable, and KWin manages to get an OpenGL 3.3 context.
