Yes I can, please find the bt attached.
FYI: My graphics device is NVidia GeForce 7600 Gt/PCI/SSE2 using the
proprietary driver.
OpenGL Version is 2.1.0 NVIDIA 96.31

This looks like a driver bug to me, and we can't reproduce it here (not
tried the same driver version though). Can you try upgrading your driver
to v97.55, or even the last beta, v100.14.06, and see if that fixes it?
Thanks,

This is the nvidia proprietary driver that gets installed by default (yast).
I'll give the beta driver a try later today and see what happens.

I have now tested with 100.14.06 and things work out fine now.
qtdemo design really has improved:-))
Unfortunately my previous installed driver version is the driver that gets
linked in by the distros autoinstaller, so I guess there might be a lot more
users experiencing this problem.
However I understand this is out of qts scope.
Thanx for your help,
Frank
