Issue description
I modify the video resolution from 1600x900 to 2560x1600. This seems to save and work for some time. However, alt tabbing to another open windows application switches the setting back to 1600x900.
Reproduction steps
Modify the Captain of Industry video resolution away from the default. Press alt-tab. When I do this, I momentarily get a black window before the other application window shows up. Then press alt-tab to return to COI and at this point my resolution has switched back to the default.
Game version and build number
