So, i stick with the latest Catalyst from ATI.As soon as I enable anti aliasing in the graphics driver control panel, the problem occurs.Here I need to say that the problem only occurs if I have no panel_as_texture=0 line in my fs9.cfg. So far, I used different drivers (old and new, even Omega and Detonator, and the RadLinker), but the problem doesn't go away using any other driver. That's a problem I have with many panels.I found the root cause of this is the anti aliasing setting of my graphics adapter (Radeon 9800 Pro).
