Qt Version: 5.3.1
Operating System: Linux 3.15.5-031505-generic x86_64
Distribution: Ubuntu 14.04 LTS

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

i went into compositor settings on system settings and changed renderign from opengl3.1 to 2.1 --> crash.
generally lots of crashes when playing arround with the compositor.. this is much more stable in kde4

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
