We've narrowed a related (hopefully the same) issue down to being
introduced in mutter!1968, which is the precursor to triple buffering.
Not triple buffering itself, but part of the same patch.

I do not experience this issue anymore (GS 44rc, 6.2 kernel, 525 Ubuntu main
driver).
Using powertop does not seem to be reliable but looking at GNOME's energy

(without any visible reason).

This might be related to a triple buffering issue:
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1441#note_1679803
If it is caused by triple buffering then you will find the issue is
temporarily fixed in mutter 44~rc (which lacks triple buffering), and
will return later in 44.0.

very normal ~ 8 W power usage.
