I was playing around trying to get my floating task bar to display glass. I realized I hadn't backed up Opus in a while so I did a complete settings backup. Just as it finished I noticed a horizontal black line across my monitor. As soon as I shut down Opus it goes away, then reappears as soon as it's restarted. I tried restoring Opus settings to an earlier date, rebooting Windows, and even reinstalled Opus with the new beta version. I'm all out of ideas.
Windows 10 64bit
was on Opus 11.16 now on 11.16.3
on a new Dell XPS 8900 Desktop
New Dell 24 inch monitor
