mouse cursor keeps jumping up and left in latest snapshot

[Christopher Zimmermann]

Hello,

today I upgraded my system to the latest snapshot from some -current 
version end of april.

Now in all gtk application my mouse cursor often jumps to the upper 
and/or left edge of the screen (not of the application window).
I already recompiled gtk+2 and some of the gtk2 applications, but it did 
not help.

Does anyone else have a similar experience? Any ides? The only idea I 
have is reinstalling the whole system :(
