Comment 10 for bug 1001936

Same problem can be reproduced when with menubar:
1. Open nautilus
2. Drag window by clicking and moving window with empty menubar or toolbar area
3. Click to any menu entry on menu bar.
4. Go out of menu
Sometimes window jumps right-down and becomes grabet until mouse click

And most annoying for me is ShotWell:
1. Open any image
2. Open color correction dialog
3. Move dialog somewhere
4. Click and drag levels slider
5. Release mouse button
Once again dialog jumps somewhere.

Bug seems related to xfwm both 4.8 and 4.10. I can't reproduce this bug with fluxbox
