I use Teamviewer on Ubuntu (Not sure if the problem is the same on Windows).
Whenever I use Alt+TAB to change the focussed window on my computer to another window while the remote window has focus
the remote window catches the Alt keydown event but not the Alt release event! So when I get back to the remote Teamviewer window the remote computer still has the Alt Key stuck pressed.
How can I prevent that the Alt-key gets stuck on the remote computer?

This creatively titled TeamViewer support thread discusses this problem, and unfortunately the response from TeamViewer was "cannot reproduce."
Even though that thread is for Windows, some of the workarounds discussed are system agnostic, and should be faster than using CompizConfig.
In my experience, option 1 works to release a stuck key.
