Description timcesq 2016-04-01 21:59:47 UTC 
Below, in Additional Informaton, is the error report generated by the Crash Reporting Assistant. I could not make it send mu report, because, apparently "version 4.11.11 is not active".



Reproducible: Always

Steps to Reproduce:
1. Go to Desktop Effects - System Settings
2. Change Compositing Type to OpenGL 2.0


Actual Results:  
"Kwin crashed"

Expected Results:  
Not a crash, I guess.


Application: kwin (4.11.11)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.19.0-32-generic x86_64
Distribution: Linux Mint 17.3 Rosa

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

Attempting to change the 'Compositing Effects' option to 'OpenGL 2.0" under Desktop Effects - System Settings.
After the crash, the Desktop Effects window show a bar which says "4 desktop effects could not be loaded". The details say that the Blur, Cover Switch, Desktop Cube and Startup Feedback all require OpenGL.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault

Possible duplicate of 320000. However, 320000 is supposed to be fixed.
Comment 2 Thomas Lübking 2016-04-01 22:18:29 UTC 
Yes, is duplicate.

Bug #320000 is *not* resolved as "fixed" but as "upstream", ie. it's clearly a bug in the VBox GL driver, ie. oracles problem. There's nothing we could do to prevent/fix this crash.

But "width=1463, height=968" means it's not because of some texture size limitation (2048)
