--- Comment #20 from Alexander Dorofeyev alexd4@inbox.lv 2008-06-29 17:17:50 --- Also, if you don't want / can't run bisect or it won't work out, maybe try bugreport to ati. I really have no idea how interested and responsive the vendors of proprietary Linux drivers are (never have to find out with nvidia, fortunatly :D), but you may try to send ATI a report, via whatever means are available. Perhaps they'll show interest. Unfortunately, at this point the details about his bug are not as good as ideally they would be, what is known is that glDrawPixels for some reason is only updating a smaller subsection of drawable.
