when i fullscreen my game on the instance im playing on, all the instances would freeze until i reset my current instance that i have fullscreened example :

play windowed for 1 minute until the instances load and then go fullscreen, that's what I do. I tried to figure out what causes this and I'm pretty sure it's just windows not rendering stuff in background because it thinks you can't see it and I have no idea how to force it to render.

ic thanks for the method and explaination and yea thats kinda annoying
