trunk/xfwm4 bug?

[Auke Kok]

I'm using a 5-day old xfwm4 from trunk atm and noticed that when 
dragging windows across the sides of desktops about 1 in 5 times it 
doesn't "wrap" to the edge I drag it over but actually makes it jump to 
the other side of the desktop, thus making me hit another edge and 
triggering another wrap+desktop switch.

Since this is rather inconsistent behaviour I wonder if anyone else has 
spotted this, or my imagination is acting up, or it's just my variable 
CPU speed creating this artefact.
