yeah your opengl stuff seems broken, not much that we can do here :/ can you install/run glxgears? Does it work? Can you attach the output of glxinfo?
I can reproduce it and my opengl is certainly working - but it seems to be some general Qt issue, not specific to kubrick: the molecular editor in kalzium also doesn't display.
oh yeah i get the same ^_^
FWIW, I've tested some 3d stuff from qtexamples and it all works fine - not sure what's different with KDE apps.
