Hi,
I'm running Ubuntu MATE 18.04.6 LTS. The bug information was sadly
collected from the working configuration of the system after dropping to
an earlier kernel.
This bug is a display bug where 1-pixel horizontal lines of multicolored
corruption or occasionally incorrect screen contents appear across the
screen, particularly during scrolling or moving the mouse. They appear
intermittently, being more common near the top of the screen.
My GPU is the built-in one on the AMD A10-5750M APU, the Radeon HD
8650G. (Laptop: G505s)
I have found that this bug occurs on vmlinuz-5.4.0-96-generic but does
not appear to occur on vmlinuz-5.4.0-91-generic when booting with that
option in GRUB.
I have not yet been able to capture an image of the issue as it becomes
difficult to use the system when the bug occurs (though it appears to be
fully functional, graphics aside). If very important I can try again
later.
-Matt
