Description Roman Bysh 2013-06-26 15:47:32 UTC 
Application: kwin (4.10.4)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.10.0-rc4-1-desktop x86_64
Distribution: "openSUSE 13.1 Milestone 2 (x86_64)"

-- Information about the crash:
Tested with openSUSE Milestone 2

1. I installed the guest additions and restarted openSUSE 13.1 Milestone 2
2. Selected  Configure Desktop-->Desktop Effects-->Advanced tab
3. Switching from XRender to openGL and Native mode causes kwin to crash in the latest version of VirtualBox 4.2.14

The crash can be reproduced every time.

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

Comment 1 Roman Bysh 2013-06-26 16:17:06 UTC 
Follow Up

The Desktop Effects keeps switching back to XRender instead of OpenGL.
As a temporary fix I added the following to .bashrc

export KWIN_DIRECT_GL=1
export KWIN_COMPOSE=O2
#Note the "O" is the capital letter "O" NOT zero. 

The problem is that it worked for a while but when I added or switched effects, it triggered the crash.
Comment 2 Thomas Lübking 2013-06-26 17:36:33 UTC 
Crash is because of concurrent kconfig accesses through ksycoco.
Fix is in production.

Thanks Thomas,

As far as openSUSE is concerned, we'll see this in openSUSE 13.1 Milestone 3.
