Public bug reported:
UBUNTU 20.04.2 updated until 02/25/2021
5.8.0-44-generic kernel
xorg version: 1:7.7+19ubuntu14
I expected to have a minimally acceptable performance, just as it was
before the update.
The problem only happens in sessions with XORG, either through the GNOME
or UBUNTU session. The screen is extremely slow, with a slight increase
in the temperature of components like CPU, nothing too serious. The
animations are very slow and everything takes a long time to open or
load, absurdly.
The problem does not happen in the Wayland session.
