KDE doubling framerate Issue (imgur.com)

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

Screen mirroring is kinda shitty rn, this might get fixed with future changes for Plasma 6.4 (which make it less shitty in general). It's probably worth fixing this as a separate thing for 6.3 though, so please make a bug report about this for KWin at bugs.kde.org
