Description John Reiser 2006-01-24 04:43:38 UTC 
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.
Comment 5 Frank Arnold 2006-01-25 12:55:40 UTC 
Please try adding the following line to the Device section of your
/etc/X11/xorg.conf:

Option "AccelMethod" "EXA"

Comment 6 John Reiser 2006-01-25 19:59:32 UTC 
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
