+++ This bug was initially created as a clone of Bug #196608 +++ Description of problem: The radeon driver suffers from framebuffer corruption, which only appears to show up in gnome-panel and nowhere else. With the FC5 radeon driver I got corruption in Firefox windows too and general system stability, so I assume this problem could still be serious, despite only ever happening in a one pixel high line. Due to gnome-screenshot being broken, you cannot see one detail that might matter: this line is the pixel right above the scrolling letters and numbers of my gtik2 (stock ticker) applet. Maybe this applet is causing things to go haywire? The one-pixel high line is intermittant, in what appears to be red and turquoise intervals. It is not a continuous line, but intermittant. Causing a redraw, eg by mousing over the firefox "globe" icon, or clicking into one of the menus, makes the line go away - but it'll return later. The problem also happens without Xinerama, on 1280x1024 pixel resolution. I have not seen it on 1024x768 while setting up the system as root, but then again I did not have gtik2 running as root either :) 01:00.0 VGA compatible controller: ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)] 01:00.1 Display controller: ATI Technologies Inc RV370 [Radeon X300SE]
Created attachment 131510 [details] screenshot with red part of line visible
On retrospect, the colors seem to correspond to the same red and green that gtik2 uses in its display. If the market had been more upbeat, I bet the screenshot would have contained a mostly green line :)
