Those are all different issues. Please:
1. Log a separate bug about each issue and reword this bug to be about
only one issue.
2. Don't install 'Oibaf' if you wish to log bugs, because it is not
supported and frequently causes new bugs that we can't fix.

Title:
Ubuntu 20.04 LTS have a low video quality, bad color management and
the screen keeps tearing
Status in Ubuntu:
Incomplete
Bug description:
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:
