Just to be sure: you've "Use OpenGL 2.0 shaders" checked in "kcmshell4 kwincompositing"?

Yes, when "Use OpenGL 2.0 shaders" is checked I can reproduce this issue, if I disable it the problem disappears
Comment 4 Thomas Lübking 2013-03-06 19:43:20 UTC
It's the linked bug then. Fix is in git master (atm)

@Martin
c-p for 4.10.2?
