Public bug reported:
Ubuntu 20.04 LTS have a low video quality, bad color management and the
screen keeps tearing. I guess maybe those are part of the same problem.
I thinks that there's maybe an issue with xorg on Intel graphics card or
probably an issue with the Mesa driver. I don't really know. The screen
keeps tearing even after I did this:
sudo mkdir /etc/X11/xorg.conf.d
sudo nano /etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "TearFree" "true"

Those are the informations I collected:
