[SOLVED] VSync stuck at 75 fps instead of 144 fps

[ajdj]

I have found a solution for this problem!

Put ~/.config/kwinrc in Konsole
Add MaxFPS=144 to the [Compositing] section.
Restart your computer

Dual screen refresh rates synced to the lower one

Hello all, I have a question about display refresh rates. I have a Dell 144 hz ultrawide screen with and a 60hz drawing display by xp pen I chose that one specifically because of native support of linux. My issue starts when both are active, as the refresh rate syncs to the lower one. meaning my 144 hz syncs to 60 hz whereas without the display it works normally and settings for the display do not seem to separate the two. Is there a possibility to fix this ? Kernel: 5.16.4-zen1-1-ze…
