If I move (dragging title bar) or resize (dragging a corner) and the mouse comes into contact with a screen edge, releasing the button 1 does not end the move or resize action. It "recognizes" the button up event sometime in the next 10 seconds...really, up to 10, usually between 1 and 3. I've verified with apps, mainly by playing with text selection, that this isn't a lagging mouse. Apps recognize the button 1 up event instantly. This is in a VMware Fusion VM, run full screen on 2 displays attached to my (closed) mac book pro. I really don't think it is a VM issue, but I've not tested on bare metal as I don't have a bare metal machine to do so on. This occurs with my wireless USB mouse (Logitech M310), and with the touchpad, so I don't believe it to be a hardware issue. top, running at half second repeat, doesn't show any exceptional CPU usage, nor does anything on the system ever seem laggy. The VM has 8 GB and 4 cores, and usually I have no apps running under OS X except for VMware Fusion and only the one VM. I do all my work in Fedora (21).
Can you reproduce on real hardware? Works fine here, I doubt it's an xfwm4/xfce issue.
