Windows Terminal version

1.15.2713.0

Windows build number

Microsoft Windows [Version 10.0.22621.521]

Other Software

No response

Steps to reproduce

  1. Start Windows Terminal
  2. Whilst the window has focus, a small grey square can be seen in the top left of the monitor
  3. Activate your keyboard shortcut to hide the terminal window (for me, Ctrl+`)
  4. The small grey square disappears, but a bigger grey rectangle now appears in the bottom-left of the monitor, just above the task bar.

Expected Behavior

There should be no grey square or rectangle.

Actual Behavior

A grey square and grey rectangle (which one depends on what state WT is in; hidden vs. visible) appears on your screen above other applications. Please see the video below:

Just solved this; it's actually a problem resulting from using MicaForEveryone. It can be solved by updating to the latest MicaForEveryone version, and then adding a specific Process rule for OpenConsole and using the following config:
