> Upstream Gnome 46 made a lot of changes recently to improve performance and input lag in Gnome-Terminal. Those changes are separate from this bug.
Exactly.
> I don't know whether those changes were backported to Ubuntu 22.04, which ships Gnome 42.
They weren't, and almost certainly won't be.
> the graphs are only talking about lag in the neighborhood of 40-50ms, which is probably just barely perceptible.
Exactly. If anyone's having latency problems big enough that make them follow this bug and try mutter packages from a PPA, then upgrading the terminal won't fix them.
