If this is still happening then it might be explained by the Mutter
frame clock over-scheduling frames such that 4 are in flight instead of
the usual limit of 3 for triple buffering. If that's the case then it
should be easy to just increase the limit, but I should note only Nvidia
on Xorg is affected. So for most people that just means Ubuntu 22.04 or
24.04. Future Ubuntu releases won't default to Xorg and likely won't
even have it as an option.
