Public bug reported: >From what I've tested: full-screen applications such as games running at non-native resolution (for example, a 1280x720 fullscreen game running on a 1920x1080 desktop) have weird scaling / stretching issues. Alt+Tabbing and re-selecting the application can sometimes fix it, but there are circumstances in which this won't work, such as a notification appearing.
It's as though Unity tries to redraw the application back to the desktop resolution which is larger than the game resolution, so you only see a stretched top left corner of the game. Here is a video I recorded showing the issue in OpenRCT2: https://vid.me/Ocyj Notice how when I change the volume (causing a notification) the game is stretched to 1920x1080, and goes back to normal once the notification fades. Note on my screen I only see the game part, and the rest is only visible from the screen recording. Here is another screenshot showing the same happening under wine: http://i.imgur.com/rOBEEub.png I'm reporting this under Unity as the above works perfect under GNOME.
