Symptoms

Infinity: Battlescape appears to work 100% perfectly, for now, aside from a minor annoyance(others may find this problem much more frustrating, depending on how fast the game loads for them) involving the options menu. Opening the options menu and navigating it works fine, up until it is closed by either applying changes or cancelling. The options menu will close, but mouse input will no longer work. The only way to resolve the issue is to quit the game with ALT-F4 and reload. It will save your options, but of course you'll need to reload the game.

The options menu bug is worked-around by alt-tabbing away from the game and alt-tabbing back.

Reproduction

Simply open the options menu, either in the main menu or while playing, and close it.

No source file or test is named. Start by reproducing the options-menu sequence in Proton 5.0-3 on Linux and inspect steam-1079620.zip alongside the system information report. Done means closing or applying the options menu leaves mouse input usable without requiring an alt-tab or restart.
