This has been happening to me since Windows 11. I can't believe Microsoft hasn't fixed it in an update yet.
Especially annoying is that the markup screen displays partially off the screen. I have to move it left before I can make it full-screen.
I've tried everything to correct it back to how it was in Windows 10 (perfect), but to no avail.
I can't wait for a fix as I use Snipping Tool multiple times/day.
