Thank you for your bug report. Is that still an issue in the current version? What do you do exactly to trigger it?

Thanks for your reply. Yes, it is still an issue: When I trigger the workspace switcher with Ctrl-Alt and an arrow key, then press the tab key and then release all keys, the workspace switcher does not disappear.

Kind regards,
Martin

I am getting this behavior without having to hit tab.

I always re-bind my workspace movement keys to super+left, super+right. With the latest up-to-date 12.04, switching workspaces with these keybinds leaves the 'Viewport Switcher Preview' window up when I release the keybinds. I must then hit escape for it to go away.

I have exact same problem as Brian: as my workspace shortcuts are involving Super and not Ctrl+Alt, Ctrl+Alt are never released and the workspace switcher stays.

To reproduce this with the normal shortcuts, it's a bit more complex than what is in the bug description:
 1. Go to top-left workspace
 2. Press Ctrl+Alt+Right
 3. Release Right
 3. Press Tab
 4. Release Tab
 5. Release Ctrl
 6. Press Tab
 7. Release Alt+Tab
=> All along the workspace switcher stayed over, and is still there.
No key works, and the cursor is invisible until your press/release Ctrl+Alt.

I'd say the workspace switcher should disappear much more easily. At least disappear as soon as the key combo which was used to initiate is not anymore fully pressed.

Also, a pretty good kludge would be to always hide the workspace switcher when _no_ key is pressed.

Yes I am having this problem as well, but it doesn't happen in my desktop only in the laptop.
