[Bug 1936754] Re: screen display: the last pixel column (on the right) is displayed on the left

[Jacob Rodgers]

I also have the issue on the Raspberry Pi 400. To add a bit more
information, the issue persists when I change resolutions, and also
occurs if I use a different monitor. I have not seen the issue on any
other operating systems.

Title:
  screen display: the last pixel column (on the right) is displayed on
  the left

Status in linux-firmware-raspi2 package in Ubuntu:
  New

Bug description:
  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.
