Public bug reported:
on the screen the first column of pixels (on the left) is weird.
Actually it appears to be the most right column that's displayed there.
The whole screen is displayed shifted on clomun to the right, and
looping so the last column right is displayed on the left border.
If you move your cursor on the right edge, it appears (one pixel wide)
on the left. Same thing if you move a window beyond the right eddge. For
example a white window, you'll see a white column on the left. (it might
be two pixels wide(?))
It does not appear on a screenshot.
It's on a Raspberry pi 400
- 20.10, had no problem. After upgrade the problem appeared.
- on a fresh 21.04 install, there's no problem either.
It appears after a package update (apt upgrade) and reboots.
'linux-firmware-raspi2' is a raw guess.
