when moving windows, window gets stucks and cursor icon jitters

[pd5rm]

I've noticed this a couple times so, and seems to occur when I use the mouse to move any kind of window.

1) Grab title area of window with mouse, left-click, hold and drag to move window.
2) The windows moves a little, then gets stuck and mouse cursor (grippy hand?) seems to jitter/get stuck in title area.

This seems to occur when left-click and mouse move operation happen very quickly. It's also hard to reproduce, maybe happens 1 in 20 times if I try to repro.
