Recently dipped into the configuration of KDE Plasma and I found something really annoying. These toolbars at the top and bottom dont disappear, when I want to play a game, even tho the game starts and is set to fullscreen mode. Additionally, this also really fucks with my mouse in a way, that I cant use the upper part of menus, because then my mouse snaps out of the window and reappears in the upper toolbar. How do I change this?
