When in fullscreen mode on Linux the window doesn’t seam to have the input focus.
Key and Mousebutton events don’t do anything.
I did a test with a click event on a sprite object which didn’t react at all.
Displaying last key pressed in a text object doesn’t update when I press a key.
The game is still running, I can disable fullscreen with a timer.
Linux Mint 17.2 Cinnamon 64Bit
