Thanks for your answers! It seems to be an OpenGL problem. If I start CS with -d3d option, it works (bad) - but it works. I tried older versions of wine before, but that didn't help me, so it must be a driver problem? I'm wondering what's the next step. Opening a Bug Ticket at Wine or ATI? If someone has an idea how to work around this issue, please let me know. I will post my results here. Thanks Sven
