I seem to be seeing a problem with the 2D display on a Radeon 8500 with the XFree86 "radeon" driver. It shows up most with the ThinIce gtk+ theme, where the ends of scrollbar thumbs show up corrupted. Also, the corners of Mozilla buttons are also corrupted. This doesn't happen on a Voodoo 5 5500, nor with the ATI binary FireGL drivers on the same Radeon card, but does with all versions of XFree86 4.2 I've tried (including the Gatos drivers and the latest XFree86 CVS trunk). Attached are some sample images of the corruption - badscrollbar.png and badbutton.png show the corruptions with XFree86 CVS trunk, goodscrollbar.png and goodbutton.png show the display as rendered by the FireGL driver (and my old Voodoo 5 displayed this in the same way).
I am supposing that this is something to do with pixel math, but I'm not anywhere near understanding where to start debugging this.
