Description Malte S. Stretz 2004-08-15 14:24:57 UTC 
As a second (Xinerama) screen I've got some weird redraw problems, especially 
if I quickly scroll something (or move it around).  I'll attach a screenshot to 
show what I mean. 
 
This happens under KDE but only on the mga screen and also with eg. Mozilla so 
I doubt it is a KDE problem.  This is Gentoo, Xorg is compiled with CFLAGS="-O2 
-mcpu=athlon-tbird". 
 
It started to happen after I switched from XFree86 (4.ummm... the last stable 
version without the license issue) to Xorg 6.7.0. On 6.7.99.2 the problem is 
still present.

I quickly scrolled around the page and the contact list with the scroll wheel. 
Note the cursor artefacts in the browser window and especially the problem with
the list in the Kopete window.

xorg.conf

I know this file is a mess, I created it years ago with SaX and hand-tuned it
the years over ;-)

	(MGAStormSync): Fix for lockups on some versions of Matrox
	Mystique. #687, Patch from Mike Harris.

It would appear then that this is a duplicate of #687, which is now resolved.

reopen this bug.

As ajax said in his comment I'm flagging this as fixed.
