Reproducible on 4.6, 5.1 versions;

Attached repro screenshots;

Repro steps:
1. Open project "ResolutionBug.zip";
2. Build to WSA and deploy on Surface 3 tablet;
3. Minimize the app, then go to "Screen resolution" settings of the device;
4. Set the resolution to the lower or lowest and apply the resolution settings; (reproduces with resolution, when you get a warning that some items might not fit on the screen)
6. Go back to the game;

Expected result :
The game is still full screen and the inputs work correctly.

Actual result :
The game is displayed in the top left corner of the screen and the rest of the screen is black, while the inputs are still mapped to the right position in the screen, resulting in inputs not being over the visual of the objects.

Project info:
In project cubes and spheres in the scene are clickable and change color when clicked to demonstrate the offset in the inputs after changing the screen resolution.

Workaround: use recommended screen resolution;
