Is anyone having trouble with Blender running on ATI graphic card with opengl antialiasing enabled? I can have up to 4x AA without any problem but when 6XAA is applied, screen curruption occurs up the the point that the interface is not usable.
I've been having this problem for the past ~6 release of Blender and all versions of ATI catalyst drivers (WinXP Pro)
"Game" card are not very effective with openGl in their drivers. so, it's not a bug, it's a feature of the driver.
turn off AA for blender.
it's not dedicace to blender. all heavy openGL charged softwares like CAD program react the same way.
