I've got similar messages:
drmn0: [drm] *ERROR* Atomic update failure on pipe A (start=293599
end=293600) time 0 us, min 1073, max 1079, scanline start 1070, end 1081

end=352659) time 0 us, min 1073, max 1079, scanline start 1057, end 1058
drmn0: [drm] *ERROR* Atomic update failure on pipe A (start=401363

end=875525) time 1566 us, min 1073, max 1079, scanline start 997, end 997
So far I've been unable to correlate them with those lags.
(Waiting for them to happen with an open windows with tail running, but,
of course, it won't happen today :)

Same here.
Further details differ, as I compile it myself.

I'not 100% sure, but I believe this started when I upgraded from 13.1 to
13.2 (with no other relevant change).

No idea, really.
If you want me to try something, collect other data, etc... I'll gladly
comply.
Perhaps a bug report should be opened?
