Desktop switcher does not disappear after switching and cause CPU usage

[autra]

Step to reproduce:
-switch desktop with the keyboard (ctrl+alt+any arrow)
-release every keys

The desktop switcher is still there and Xorg stays at around 30% CPU until I hit esc key.

I can't take a screenshot, because it won't allow me when the switcher stays on top.

Ok some precision : I have this problem only because my shortcuts weren't default one : I put super+arrows.
If I put ctrl+alt+arrows back everything works smoothly.

Any workarounds ? I really would like to keep my old shortcuts !! :-)

Status changed to 'Confirmed' because the bug affects multiple users.

Same here, using super+arrows too.

Same here. With ctrl+alt+arrows, the switcher disappears automatically. With super+arrows the switcher stays open (though enter or escape will close it).
