GNOME 46.5 seems to have the same issue as 47.0 so I don't think it's a
Mutter regression.

Bug description:
I've just tried the Nvidia-560 driver for the first time and am seeing
very poor performance in Wayland sessions. Just tapping the Super key
I can see animations stuttering.
In 'NVIDIA Settings' it looks like the reason might be a lack of power
profiles ("Performance Levels"). Those are only reported correctly if
I log into Xorg. And indeed performance in Xorg sessions is much
higher, more like what I would expect.
P.S. Performance on this machine is much worse in upstream GNOME
without triple buffering. So triple buffering is doing its job.
