Default Re: XServer hang (100% CPU)

I just dug into the X server bug AaronP mentioned, but this bug is always related to Xinerama mode. But we are using single screens (no xinerama, to twinview, see xorg.conf below).
And the behaviour described in the X server bug, is often related to some actions (mouse movement while applications window start.

Our observations are:
Many times after a long time without user action (weekend, night) the first mouse movement is the trigger for the problem. Just now the X server starts to consume 100% CPU (supervision scripts show, that this is not the case before) and mouse is flashing, moving stuck, no X changes of applications possible.

Is there a chance to get rid of the problem updating to 295.33 ?
