Rendering Artifacts with OpenGL Tnt2 and Blender
 
I'm using nVidia driver version 1.0.5336 together with XFree86 Version 4.3.0 (Fedora Core 1: 4.3.0-55)
I'm getting very ugly artifacts with Blender 2.33a: if the cursor is over an OpenGL window and the part of the window under the cursor is redrawn, a rectangular area around the cursor is redrawn by a filled monocolor rectangle.

It is particularly well visible in Blender where the artifacts generated by virtually any move of the mouse, e.g. over the menu, are so severe that the app is unusable; in case of the menus after a mouseover they are never redrawn correctly...

I have:
