When using any Nvidia driver on my system where that be beta or the latest release. Using DisplayPort causing screne lag almost like the refresh rate is 5hz. Where as using HDMI doesnt cause this issue. I have tried using a the latest LTS kernel and the LTS release before that and still the same issue. Currently I am running version kernel v5.10.16 and driver version 460.39-1 and the issue persists.
Here is a short video of what the issue looks like https://www.youtube.com/watch?v=01osxGum610
