Apps should have a way to disable HUD

[Markcortbass]

Please hide/don't display HUD in fullscreen applications. Because this can be very annoying when you run the program in full screen, and HUD suddenly appears when you are busy. One example is that when you Is gaming, and you press the ALT button. Your whole game is minimized to display HUD.

We don't want to have it not show in full screen applications as there are many content creation applications that run full screen that HUD is useful for. But, for games, it would seem that they should be able to get their alt key back.

Now that the Bug #1159249 is resolved for both 14.04 LTS and 15.04 I think this bug should get at least a higher priority.

Some users already hit this bug and they were even convinced that HUD never worked on top of fullscreen windows. This is thread from Development Version section of Ubuntu Forums.

Obviously there were be many more users hitting this bug now that HUD actually works on top of fullscreen windows.

Also there are at least three very popular games that use Alt key in their default setup for something. Those are Torchlight and Torchlight II (display of items) and apparently Dota 2.

Workarounds for users involve disabling HUD entirely or disabling it before launching the game and then enabling it again after. This is of course very user unfriendly.
