Please try a 5.10 kernel as well as a 5.4 kernel so we can get a better idea of which versions are affected:

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.
