Bug#450851: maybe another effect of the bug

["Mathias L. Baumann" <anonym001@supradigital.org>]

Hi there,

i was affected by this bug and worked around it by disabling DGA in the  
games i play.
However, i recently switched to xinerama, and the following problem showed  
up:
when turning the mouse to fast it seems to move into the other screen.  
this results in a drastical mouselag in the game (i tested 3 games, 2 sdl  
based, DGA was off in all[enabling DGA enabled also the  
mouse-stays-in-the-corner-problem]). i downgraded X to 1.1.1-21etch4 and  
the problem was gone (together with the DGA problem). it did not matter if  
dga was enabled or not then.
