Comment 1 Thomas Lübking 2012-05-31 20:50:36 UTC

crashes in glGetString(GL_VENDOR);

please record your exact GPU and driver versions (you cannot use kwin to detect them and glxinfo will likely fail as well)

the effects are likely disabled because the test crashed several times in a row before what is why you got 
#11 0x00007f9c5d42a6e7 in KWin::KWinCompositingConfig::rearmGlSupport
a warning before (this is a very basic OpenGL call and if that crashes sth. is seriously broken with the driver)

The bug is either in mesa or xf86-video-ati/ati-dri -> try other versions of those or use the xrender backend (also check whether your GPU is actually supported by the driver)
