I have multiple monitors and use Alt + Enter frequently to swap from Full Screen to Windowed mode so I can use my other screens for DIM, Discord, web browser, Slack, etc. I received the error code at the end match screen in Trials when I Alt + Enter to check a message. I also get ~40 FPS when looking at my roster in-game. The frames remain low until I exit the roster tab. I have a high-end system running a Ryzen 3800x and a 3080ti. Not being able to do either of these for another month or so without fear of getting some sort of game ban is a no bueno for me. Everyone looks at their roster when they are in-game.
