--- Comment #6 from Pedro Alves <palves at redhat dot com> ---
I did not mean a console window (Alt-Tab), I mean a virtual console
(Ctrl+Alt+Fn), which should work even when X is stuck:

most likely, you stopped the program while it was holding a pointer grab:
http://unix.stackexchange.com/questions/40458/command-for-forcing-a-pointer-ungrab-captured-mouse-release
Try switching to a virtual console (ctrl+alt+fn) and doing:
$ DISPLAY=:0 xdotool key XF86Ungrab
If that doesn't work, as a wild guess, try to figure out out to disable client
side decorations.
