I have been having the same problem, with many images, especially scaled ones. I'm gathering that this is a known problem with using XAA? The closest explanation I could find was #433331, but this is clearly not a compositing window manager.
Switching to EXA made images render correctly. On the other hand, iceweasel crashed within minutes while looking at bug reports on this subject so I think I shall try XAA again... -- Daniel Jacobowitz CodeSourcery -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
