Display error with Qt tutorial sample on linux
I compiled the Qt tutorial sample on Windows with MSVC 2010 and Qt 4.8.4 and everything worked fine. When I tried to use g++ 4.4.5 and also Qt 4.8.4 on a Debian Linux system, the application works, but there are display errors. I do "File->New", then I create the bottle. When I move the window over the desktop now, after a few movements the 3D view is not correctly redrawn. Instead I see the desktop or some grey area instead of the 3D viewer with the bottle (as shown on the screenshot).
Does anyone know the reason? Thank you very much for any help!
