Yesterday when I switched the game from Borderless Window to Fullscreen it worked like a charm, no issues. When I tried starting the game today it immediately minimized itself. When I tried tabbing back in, it remained for all but half a second before minimizing itself again. Hit Alt + Enter to put it into Windowed mode, no issues. Went into the game options, put it back into Fullscreen? Minimized immediately after, and keeps minimizing itself the moment I tab back into it.

Borderless Window works fine without any issues, so does any other game run in Fullscreen (tested with Rainbow Six Siege and Apex Legends). Verifying the game files did nothing, neither did restarting my PC.

Hey,

From what I can find there could be a number of things causing this which seem pretty random. For example:

Are you able to see what programs are running in the background as well? Just to see if there are any conflicts

Hey CaptainLad69,

Sorry to hear that, have you tried to launch the game as system admin? Do you have any other apps running at the same time that could be causing this?
