haha ok! can you point me to where other people have described themselves also having the same issue please?
OK, I'll describe one for you. ME. I get it sometimes when Windows Hello recognizes my face and puts up a lock screen that doesn't cover the full screen. So, yes, I've seen it many times.
Paul Thurrott on thurrott.com mentioned it in one of his articles. I couldn't put my finger on it when I looked just now, but it's there somewhere.
I recall it's being mentioned in this forum somewhere. I can't think of what to call it to put in a search field though.
