I’m fan of EU4, and OpenSuSE. However they do not get along well with each other in Plasma 5 & Tumbleweed.
Launcher works. Game menu works. Game map in zoom out works.
But after starting campaign game zoom in on the map… and freeze whole desktop. No input works, soft reset do not work. Switching to virtual consoles do not work (like Ctrl+Alt+F1). No specific message in Steam logs.
