Hi there again,

I'm using opensuse 13.1 x86_64 with an nvidia 7950 GX2. I have downloaded the "legacy" latest official driver from the nvidia site, i.e. NVIDIA-Linux-x86_64-304.116.run, I get it compiled and installed, So far so good. I can get KDE4 with almost all the graphical opengl effects.

However, when I want to display a Qt 5.2 quick example, typically with qmlscene, my screen blackens 1 second before displaying its window. But when I run i.e. glxgears, I don't get this artifact.

Same behavior with previous versions of opensuse and official drivers.

what's the problem ?
