Bug 449160

video demonstration

SUMMARY
My main monitor with 1440 vertical resolution and second monitor with 1024 on vertical. Second monitor placed in right-hand of primary monitor and centered on vertical. So second monitor has position +2560+208.
On second monitor there is a plasma panel on top.
When I move window on primary monitor by vertical axis from bottom to top it sticks/snap/hangs around +208+24 position and can move further only after mouse pass +208 position.

Despite some weird recording artifacts I show it on this video https://youtu.be/SZSH1JiTtFg

STEPS TO REPRODUCE
1. Setup second monitor on side of primary and offset it by vertical.
2. Place plasma panel on top of second monitor
3. Drag window on main monitor from bottom to top

OBSERVED RESULT
Window snaps at some point on main monitor, right when pass height where placed panel on second monitor.
It also snaps when moved from top to bottom.

EXPECTED RESULT
Window should be moved smoothly from bottom to top and top to bottom on this monitor.
