I started using Ubuntu 20.04 two days ago, and this has been a nonstop issue. There would be constant screen tearing.

Now, I did come to this forum and tried the many solutions. Such as these two:

Screen tearing in Ubuntu with Nvidia/Intel graphics

Screen Tearing on Ubuntu Xorg 20.04 with Intel Graphics

However, none of them work. If anyone can help me out with this issue, I'd really appreciate it. Thank you.

Also, I'm still very new to Ubuntu, so please bear with me.

UPDATE: I did try the dri3 method. While it seems to work, the screen and mouse cursor needs to be absolutely still. I've given up at this point for now, but if anyone is still willing to help, I'd really appreciate it.

These are my specs:

  • CPU: Quad Core Intel Core i5-8265U (-MT MCP-) speed/min/max: 600/400/3900 MHz
  • Kernel: 5.4.0-33-generic x86_64 Up: 9m Mem: 1877.9/15899.4 MiB(11.8%)

I have the same problem with Intel UHD 620 on Thinkpad T490. I don't know why but changing from Xorg to Wayland resolve the problem. However videos played with VLC/Chrome browser don't have this issue.

To fix the problem with Firefox you need to type in the URL about:config. After "Accepting the risk", type in the search bar layers.acceleration.force-enabled and set it on true.

I personally don't like this solution because it seems to be a system problem with Xorg. I checked on Xubuntu 20.04 and Kubuntu 20.04 and both don't have tearing at all.

Hoping to find a real solution soon.
