Does this only happen with DRI2?

Yes, I also tried EXA, which is fine.
Actually I suspect it is a UXA issue.

I am seeing the same with gkrellm and the "Demaximize"-button in the KDE B2 window border theme(the other buttons are unaffected).

Catch solid fills to 1bpp targets

This patch fixes my problems. Perhaps the original problem is fixed, too?
Comment 8 Eric Anholt 2008-12-05 12:28:49 UTC 
Actually, it's anything <8bpp for solid and copy.  Huge thanks for tracking down this issue.

    uxa: Reject solid/copy to under-8bpp destinations.
    
    EXA wouldn't create pixmaps for under-8bpp, but UXA does.  Fixes
    mis-rendering in xfwm, evolution message compose, firefox link
    drag'n'drop, and I'm sure more.  Big thanks to Pierre Willenbrock for
    debugging the issue!
