Hey, I am currently using two monitors: 1. 144Hz 1080p 2. 60Hz 4K The 144Hz monitor is the primary one. Both are up and running. If I start firefox in fullscreen on my main monitor it is at 60hz refresh rate -> stuttering. If I just run it in window mode it is smooth. If my 4k monitor is turned off i can run firefox in fullscreen mode and dont experience any lags. Other applications are fine. Nothing is lagging except firefox. Can I set the refresh rate in settings or something like that?
