Ubuntu – Screen Tearing Ubuntu 18.04

Yes I finally have a solution for you it took a bit of digging, you have to use CompizConfig Settings Manager. Go to Utilty > Workarounds, make sure this box is checked:

Also should be checked:

• "Don't wait for video sync"

• "Force full screen redraws"

  

Also some other this you could do is in the CCSM go to "OpenGL" click on the texture tab put Best:

Then go to "Composite" and uncheck "detect rate" then crank up the refresh rate to anything higher than it's default that is set at 50 I set mine to anything beyond 60.

problems. Hope this helped. :)

Reinstall the Graphc driver:

sudo apt-get --purge autoremove xserver-xorg-video-radeon && sudo apt-get install xserver-xorg-video-radeon

Then reboot.
