Oh so it also happens with DRI1. It would probably be easiest (as others have suggested) to do a git bisect then. Alternatively, since this appears to work on r200 but not r300, you could try finding differences wrt front buffer rendering between those drivers manually - it seems unlikely this still happens to work with git master on r200 but not r300 since pretty much all of the code which could affect this issue should be shared.
