Comment 140 for bug 729979

To be honest, I think the original problem that bug 729979 presented would have been fixed at revision 3220 in lp:compiz , since I know the code that generates mipmaps during animations was fixed for NVIDIA drivers. The focus animations use mipmaps, and incorrect usage of mipmaps generally leads to white textures.

Invisible windows are something else. Which I'm looking into now.
