Xfce panel/Qt oddity testcase

Test case:
 - $ ./test.py
 - Press F for fullscreen, then H to hide menu -> xfce panel is still shown

Bonus oddity:
 - $ ./test.py
 - Press H to hide menu, F for fullscreen -> works fine

 Compare to:
 - $ ./test.py
 - Press X to hide menu AND switch to fullscreen -> xfce panel is still shown

 However:
 - $ ./test.py
 - Press H to hide menu, press X to show menu AND switch to fullscreen -> works fine
