Describe the bug After flashing the reTerminal with the latest Raspberry Pi OS Bullseye found here, the LCD has orientation problem with auto-rotate function.

Expected behavior It works well with RPi OS Buster

Tests performed

Test 1 with Bullseye and these changes:

  1. As soon as overlays are installed, the screen looks like this:
  1. After following these instructions and reboot the device, the device orientation looks normal
  1. However, when I lift the device and place the device in landscape orientation, the orientation changes
  1. Landscape (flipped) has same issue
  1. Portrait and portrait (flipped) have no issue

Test 2 with Bullseye without any changes:

  1. As soon as overlays are installed, the screen looks like this:
  1. However, even without following this, the screen behaves the same as 2,3,4,5 in test 1 above.

In conclusion, no matter whether we follow this or not, the screen behavior for auto-rotate is the same.

Thank you.

Best Regards, Lakshantha
