Bug Description

At random intervals the screen suddenly pixelates.

The issue does not happen when using the linux kernel v4.17.19-041719 but happens when using other kernels greater than v4.17.19-041719 upto and including 5.0.0-8.9

Please let me know if you need any other logs and I can provide the same.

Oh, sorry. You seem to be using unsupported graphics drivers from "oibaf".

Please remove those using ppa-purge, reboot, and if the problem persists then reopen this bug.
