From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux ppc; en-US; rv:1.8) Gecko/20060103 Fedora/1.5-4 Firefox/1.5 Description of problem: Under Fedora Core 5 test 2 on Apple Macintosh Mini (PowerPC 32-bit), dragging a window does not restore the background on the trailing horizontal edge. The trailing vertical edge is OK. Version-Release number of selected component (if applicable): xorg-x11-drv-fbdev-0.1.0.4-1 How reproducible: Always Steps to Reproduce: 1. Drag a window (move the pointer to the title bar, press and hold Button1, move the mouse.) 2. 3. Actual Results: The trailing horizontal edge leaves "ghost tails" instead of restoring the newly-exposed background window. Expected Results: The trailing horizontal edge should redraw the newly-exposed background window. Additional info: Will attach xorg.conf (created by anaconda) and Xorg.0.log.

The badness happens only when the Desktop is the background window. Application windows (at least: gnome-terminal, Firefox) that are exposed by drag get [re-]drawn properly.
Please try adding the following line to the Device section of your /etc/X11/xorg.conf: Option "AccelMethod" "EXA" It might be related to this Xorg bug: https://bugs.freedesktop.org/show_bug.cgi?id=4456
Thank you, Frank. That works. The Desktop (root window) is redrawn properly on the trailing horizontal edge of another window being dragged. The complete Device section is now: ----- Section "Device" Identifier "Videocard0" Driver "ati" VendorName "Videocard vendor" BoardName "ATI Technologies Inc RV280 [Radeon 9200]" Option "UseFBDev" "true" Option "AccelMethod" "EXA" EndSection -----
