OS: Ubuntu LTS 16.04
PC: FullHD monitor, Intel HD Graphics 530, no external videocard

In landscape orientation all is good.
In portrait orientation I have screen tearing problem, like this: https://en.wikipedia.org/wiki/Screen_tearing
When I move some small window across the screen, screen image tears in random horizonal lines.

I tried this (as someone suggested in similar questions):

sudo apt-get purge xserver-xorg-video-intel

After reboot problem changes: now when I move small window across the screen, I clearly see tearing in only one same vertical (!) line at the right (at around 800px of 1080px screen width, didn't meaasure correctly). So I reverted this and installed xserver-xorg-video-intel again.

Also tried this solution:
Screen tearing in Ubuntu with Nvidia/Intel graphics
But after creating /etc/X11/xorg.conf.d/20-intel.conf sytem won't boot.

Here's how I solved this - on Ubuntu / Pop OS 20.04

Enable Wayland by editing the file /etc/gdm3/custom.conf

Change

WaylandEnable=false

To

#WaylandEnable=false

Reboot. When you log in, make sure to choose "Wayland" as part of your Desktop environment.

My rotated screen doesn't tear!

Using Wayland has solved this issue for me as well. I am using a Thinkpad T470 with integrated graphics and an Ubuntu 20.04 installation. I tried many solution to solve the tearing issue, but only this one worked. Side note - I am using an external monitor connected to the Thunderbolt port. Another thing I had to do was to comment out all the lines in

/usr/lib/udev/rules.d/61-gdm.rules

albeit I could probably leave the Nvidia line in my case.
