Dual screen problem with fullscreen games

Hello, i’m new on Manjaro, and i have a little problem. I’m usung a dual screen with a kde desktop. When i have a game in fullscreen on one monitor, it reduce it automaticly when i clic on my second monitor to do something else at the same time… I had no problem on Windows os before. Maybe i forgot something in the options :face_with_raised_eyebrow:

Thanks for help ^^

Set the game to run in borderless fullscreen windowed mode.

Cannot. Just have fullscreen OR windowed mode

Some games support it, some don’t.

thanks anyway
