--- Comment #6 from Michal Suchanek <[email protected]> 2011-12-15 15:07:36 UTC --- This is hard to tell. On the e-450 the corruption is present with the earliest driver I could get working. On redwood the corruption happens only rarely but as far as I remember ever since I got the card which is again since it got supported. With the r300 card the corruption only happens recently which besides some upgrades coincides with turning off vline waits which might put more load on the card or cause races that would not happen otherwise. It is not reproducible reliably, however, so not something bisectable. I tried experimenting on the e-450 which shows most corruption and found that running firefox causes the corruption (in firefox and elsewhere in gtk). When firefox is closed corruption ceases immediately on next redraw. gtk seems to redraw every element on mouseover so wiggling the mouse pointer over a treeview or a pulldown menu causes a lot of drawing I would guess. The corruption is visually very similar to what I see on the r300 so I guess it's something caused by the driver and the way gtk is drawing, not the hardware. There are pieces of text which are skewed, show garbage or different text in the text color, show a blob in text color approximately the size of the text or less often complete garbage and pieces of different textures. The corruption lasts until redraw. Another way to get the corruption is to configure a lot of applets in avant window navigator. I tried to boot an openSUSE GNOME live CD on an e-350 and it was free of corruption initially. However, opening cover links from addons.mozilla.org, wikipedia.org and wikinews (over 100 tabs total) gives reliable temporary corruption in gtk menus (that is the menu is shown corrupted and redrawn immediately). It seems openSUSE uses some different GTK build because the menus are typically corrupted whole, not per item as on Debian/Ubuntu. -- Configure bugmail: https://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
