Ubuntu 21.04 (hirsute) reached end-of-life on January 20, 2022.

Using 'Ubuntu on Xorg' instead of 'Ubuntu' also helps. Because the
former having more layers and less internal blocking actually dabbles in
triple buffering sometimes by accident. Although I'm not sure if that's
the reason it's smoother or just Xorg adds extra GPU load.
Since the default 'Ubuntu'
The issue has always existed. But with such a sharp edge between smooth
and stuttering any slightest change in the GUI can push it over the
edge. Also a little annoyingly, as we optimize more code it can
sometimes make the problem *worse* as the GPU becomes less loaded and
less likely to up-clock
That sounds like a heavy solution to lock the frequency at the max.
How come this issue wasn't there in PopOS 20.04 (wayland session)? Was
there a regression somewhere in the stack in 21.04, or is PopOS doing
its own tuning? I haven't tried Ubuntu 20.04, nor PopOS 21.04, to know
whether PopOS was
I was just trying to avoid getting people's hopes up but most likely
finished within months. Triple buffering itself is finished but it
breaks the Wayland backend so that needs fixing yet.
And yes there is a hack to make an Intel GPU perform better at the
expense of power and heat:
cd
Years? Ouch. That's a bit too much. I understand that the switch to
triple buffering can be a lot of work, but isn't there some hacky
solution to improve the situation in the mean time? Something like
manually telling the GPU to be in the same mode that it's in when an
external monitor is
Yes gnome-shell/mutter currently causes the GPU to stay in low power
mode too much, unless you add extra demand.
This will be fixed in
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1441 or similar
but it will take some months (or years) to complete.
