And that solved the issue, I take it? Edit: I don't have Discord, but I think you don't need to have the main program running for the overlay to be active. I believe Discord has it running as a separate task in the background? It must be some overlay causing the issue or else you would not be able to run it in fullscreen mode (if the window was on the wrong, non-existend second screen the game would run there when you select fullscreen).I tested it a couple of times now and it seems to be working fine. Even when Discord is running. The amount of crashes also reduced. I am not a Discord pro but due to the constant updates and automatic changes to the user settings, I wouldn't be surprised if it truely was the source of the issue. Thanks to both of you for your help! :)
