Problem:
1: When using Alt-Enter to toggle between window/full-screen modes, the game screen becomes a solid brown block (which slightly changes color every few seconds).
When this occurred, it could be reproduced with 100% certainty - every Alt-Enter after game startup would cause the “brown screen”, whether from Windowed to fullscreen or vice versa. This is hereafter referred to as “error state”.
2: During the period in which the Alt-Enter issue was present, trying to change the Skirmish map Biome would crash the game.
3: When I tried to change the display mode from Windowed to Borderless Fullscreen in the Settings menu, the menu becomes glitched:
Some UI items still become highlighted when moused over, but do not respond when clicked. When I clicked on Credits, the game crashed.
4: The error state was gone after restarting the game, and repeatedly using Settings to switch between display modes. The game functioned normally afterwards.
Version:
5.0.26139.0 (see screenshot above).
Though to my memory, components of the issues had been occurring sporadically since the beta.
Hardware:
See screenshot above.
Notably, I’m using a laptop which built-in screen has a different native resolution from the external monitor - a common source of issues in many games. The error may be related to mismatch of expected & actual resolutions.
