Description Heikki Välisuo 2013-12-15 21:20:06 UTC

Application: kwin (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.5
Operating System: Linux 3.12.5-3.g48b587a-default x86_64
Distribution: "openSUSE 13.1 (Bottle) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

Enabled openGL 3.1 compositing. Kwin crashes always. Tested many times. Usually turned to openGL 2.0 and worked OK. This time (after intalling the debug symbols. Sorry I do not remember if I changed anything else) runs still with openGL 3.1 but with the effects do not work (I only have present windows and present all desktops)

Qt graphics system = raste, tearing prevention automatic  

This is no problem for me. openGL 2.0 and xrender are fine for me. Just forget this if it seems useless for debugging.

-- Backtrace:
Application: KWin (kwin), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

afawk it's a driver bug only.
also your gpu/driver  willlikely not support gl3.0 anyway - check the dupe for details

Comment 2 Heikki Välisuo 2013-12-16 08:32:50 UTC

I have an intel core i3-530 CPU (Ironlake). If I understood correctly, it does not support openGL 3.1.

When I set compositing to 3.1, kwin crashes and restarts using openGL 2.0. Works fine.

I am sorry I did not do my homework before reporting the "bug".

 RESOLVED?

Comment 3 Thomas Lübking 2013-12-16 14:40:03 UTC

It's not your fault - of course the driver should not crash just because it doesn't support a configuration, but simply fail to allocate a context, return NULL and at some point create a context.

If that wasn't the case, KWin would have to not try (it knows that the core profile is not supported)
