KDE doubling framerate Issue in c/kde@lemmy.kde.social

Hey thanks so much for replying, currently using amdgpu. GPU is an AMD 7900xtx. Heres the output of lspci -v for the GPU.

Any idea how i can narrow it down to know if it is a kwin_wayland issue or driver?

I'm having issues with KDE seemingly doubling my monitors refresh rate in small bursts, which is causing stuttering and smoothness issues.

A bit of background on the setup:

I have a 1080p monitor at 144hz a 1440p monitor also a 144hz external capture card that is a duplicate of of the 1440p monitor also able to accept 144hz.

What I'm seeing is the main monitor (1440p) frame rate with jump between 144 and 288fps refresh rate and i'm not sure how to stop the behavior or even really how best to start troubleshooting it.

Any advice would be awesome
