Start with the BackwardChar entry in the reported stack trace and compare it with the full-screen and windowed BufferWidth and BufferHeight values. Try the described Windows Terminal resize and wake sequence, then determine whether it can be made to complete without the console cursor-position exception; the issue is done when the transition no longer produces this failure.

Screenshot

I had left my Terminal in full-screen mode for a long time. (Note, background image is an animated GIF. I don't know if that's relevant.) The last thing on the display was an output of "ls."

Full screen screenshot:

The display went to sleep after some time (~1 hour). I came back to the computer after a while and tried to wake it up by repeatedly hitting the space bar. I woke the display (which I think was still normal?) and then tried to take Terminal out of full screen mode. I hit Esc but it stayed full screen. I couldn't remember the key to take it out of full screen (I believe I tried F11). I must've hit something that worked, because the Terminal window switched from full screen to windowed... but then I saw the PowerShell exception.

Windowed screenshot:

Image

The exception seems to be saying I had entered hundreds of "LeftArrow" characters? Which I can assure you is not the case: I don't think I hit "Left Arrow" once during this time I was trying to exit full screen.

Obviously the window size changed when I hit F11 to go from full screen to windowed. The BufferWidth and BufferHeight changed:

Full screen:

  • BufferWidth: 179
  • BufferHeight: 49

Windowed:

  • BufferWidth: 119
  • BufferHeight: 38
Environment data
FULL SCREEN:
PS Version: 7.5.2
PS HostName: ConsoleHost (Windows Terminal)
PSReadLine Version: 2.3.6
PSReadLine EditMode: Windows
OS: 10.0.22000.1 (WinBuild.160101.0800)
BufferWidth: 179
BufferHeight: 49

PS HostName: ConsoleHost (Windows Terminal)

Steps to reproduce

I cannot seem to reproduce doing the steps I performed before (full screen with alt-Enter, exit full screen with spacebar/Esc/F11).

Expected behavior

No exception expected. No references to repeated presses of "Left Arrow" key expected.

Actual behavior

The above exception happened once.
