Try this setting: Display Configuration > Screen tearing: Allow in fullscreen windows. Whatever it’s set to, try the other setting. I had a similar issue once and this fixed it. The issue came back a long time later and switching it again fixed it. 🤷‍♂️

It’s a difficult issue to pin down. I’ve also read about video stuttering while trying to stay synched to pipewire audio which is having buffer underruns, even if your audio sounds fine. To check the audio buffer, you install and run pw-top and then watch it while you are having the video problem.

It’s not the fault of the creators of an operating system that Nvidia refuses to write comparable drivers. Nvidia are the only ones with the technical knowledge of the GPU’s internals that is necessary to write the 100% functional driver. Open-source Nouveau drivers exist but are less functional because of this, its programmers have to try to reverse-engineer and do a lot of guesswork and testing, and for free.

Basically: If you value FOSS software at all, buy from manufacturers that are friendlier to FOSS software, or you may unknowingly lock yourself out of it.

Edit: Buying newer (especially of Nvidia) is probably a bad idea if you intend to run Linux. Older cards have had more time for them to fix the inevitable bugs. I run a GTX980Ti 😅 with the closed-source drivers on an Arch-based system and I’m honestly surprised a video driver update hasn’t seriously broken anything yet.
