• Description:
  If you try to rotate one of the screens with video=HDMI-A-1:panel_orientation=upside_down kernel parameter or other transformation on KMS level, the screen video output is rotated correctly without transform on the Sway's side. However, the input (and cursor visually) is kept how it would be without the transform. So I get the correct video, but flipped inputs. map_to_output didn't help and would be a bad restriction anyway.

• Video
  I've tried to record a video and observed a funny behavior. Right when I start screen recording, the input fixes itself and still works even after I stop the recording. But as soon as I leave the screen's workspace and re-enter, it's broken again. I record using wf-recorder and the full script can be found here.

• Why
  Rotation on the KMS level helps to avoid transcoding screen recordings or the use of rotation metadata (that causes issues way too often). It also rotates the tty, which is nice.
