Thanks for the response.
How come I've only noticed this running Ubuntu 24 or Debian 12 with gnome and

years?
I would expect high CPU usage when doing complex operations or graphical
activities, but this is just the des

High CPU usage when software rendering

If you can find a graphics card that is not Matrox, like AMD, Nvidia or
Intel, then that should work around the issue.

GNOME is not well optimized for software rendering. But GNOME is not
alone there... It just uses OpenGL for everything and Mesa implements
OpenGL either on a GPU or by using a bunch of CPU cores(!). So really
it's GNOME's fault for not having a true native software-rendering
backend to bypass Mesa.
High CPU is probably expected here. The Matrox graphics card does not
have a GPU so the system has to emulate a GPU on the CPU. Hence very
high CPU usage.
