I see you were fortunate enough to not use notepad aprox 5 months ago, when they were running the rich formatting preview. It was on by default, and would drop around 5% of the characters you type. Literally failing at the only thing it's supposed to do. I repro'd this on 2 out of 2 machines.

Maybe they fixed it, maybe they haven't. I both turned off formatting and am using vscode for notes now.

I think I had to disable spellcheck to fix the ignored keystrokes, it happened even after disabling formatting

ahh, it might have been spellcheck then. I turned off all that stuff. In the heat of the moment, maybe I was a bit too angry to do proper root cause analysis :P
