I have 2 monitors and even with just one I always have to tab out of the game if I want to reply on Discord etc. This causes the game to lag over time until it crashes. In borderless windowed mode I can't move my mouse out of the game frame. I'm forced to be in full screen all the time, even if I set a smaller screen resolution I can't get out. Its frustrating because often you want to write with a few persons but not really talk to them because they talk into your gamestorys. I was already on Game property and put on disabler fullscreen optimization.
