[E-devel] Alt+Tab bug

[Sthithaprajna Garapaty]

Sometimes, when I alt+tab very quickly(press alt+tab and release both keys quickly),
the alt+tab window gets stuck and the mouse gets stuck with it.
The mouse can only be freed by pressing alt+tab again, which also returns the alt+tab window to normal behavior.

This happens quite often and is easily reproducable.

Please fix this as soon as you can.

Thanks!
