--- Comment #5 from Matt Turner <[email protected]> 2009-08-10 10:09:25 PST --- Created an attachment (id=28488) --> (http://bugs.freedesktop.org/attachment.cgi?id=28488) Screenshot of corruption I grabbed the screenshot with xwd, but it is not representative of how the corruption actually appears on screen. For instance - in the screenshot, the background is garbage, but on the screen, it's just black (which I think is normal) - text appears in the screenshot, whereas no text appears on the screen - the borders are corrupted in the screenshot, but they are drawn file on the screen The three red lines mentioned before turned out to be the totally-corrupted cursor. Turning on SWcursor causes the cursor to not be drawn at all. Option "EXANoComposite" "true" causes all text on the xdm login screen to not be drawn. Option "EXANoUploadToScreen" "false" causes more corruption. Dave suggested on IRC last night that it may be either a cache problem or an oversight with page sizes. Notes: (1) Page size on Alpha is 8K. (2) Alpha is extremely relaxed with memory ordering (see Documentation/memory-barriers.txt in the kernel), and (3) Alpha is entirely cache coherent by design. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
