Comment 9 for bug 1040303

See comments in the Hedgewars bug.

This appears to be a confusion by the user as to what fullscreen mode in a game means (as opposed to a maximised game window).

IF this is happening in a maximised window (not fullscreen mode, just maximised window) it might be an issue with the fact that Unity triggers the menu when you mouse all the way over to the left, and the game, like many games that use the mouse, takes control of it with Warp Mouse in SDL.

That's not how the bug was described, but I suppose it is a possibility. In that case the Unity menu would still show up if Super was pressed.
