Bug Description
When no external monitor is connected Gnome Shell activities animation is sluggish. Once an external monitor is connected the animation becomes noticeably smoother. It looks like the OS is not properly responding to the extra processing demands by raising the CPU/GPU performance, and having an external monitor connected somehow triggers a higher performance level.
This is on a System76 Darter Pro machine with Intel® Core™ i7-8565U and Intel UHD 620 running Ubuntu 21.04 in Wayland session.

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.
