lost mouse events

[Matthew Woehlke]

I haven't figured out the cause of this, but it occurred to me just 
recently that it might be kwin-related... I have this problem where 
periodically (i.e. "usually several times per day") my desktop (KDE 
trunk) stops responding to mouse events. The cursor still moves, the 
machine otherwise works normally, but all mouse clicks are apparently 
sent to /dev/null.

The darndest thing is, if I fire up KVM (Win XP guest), let it boot, and 
do an OS shutdown, the mouse works again. (SDL grab+release doesn't fix 
it, starting KVM and shutting it down doesn't... it has to go through 
booting XP and shutting down XP, and when kvm goes away it works again.) 
But it isn't a kvm problem because it can break when kvm isn't running.

xidump shows that the mouse events are getting into X.

Any thoughts? Any guesses what to blame, or how to debug?
