Not all, but several. At first I thought it was because I was in full screen mode, but even when I resize the RU box down to 1/4 of my screen it keeps happening.
Maybe it's due to the version of 10... I know some of the machines are on the newest update, while others are not. But I'm not sure which are which. I only remote in when needed and most of the time someone is there, so I'm not even dealing with the login screen, making it harder for me to be sure which machines have the issue.
