Comment 8 for bug 553647

Sorry for editing to my taste, apparently I have too much rights. If you would like to know, I trigger this bug by pressing a ShapedButton (like the one with the Italy flag) in wxPython demo (wx2.8-examples package). (That widget also draws a black circle/ellipse.) The computer has ATI Technologies Inc RC410 [Radeon Xpress 200] video card, and radeon driver is used.

Is it a release critical bug?
