White Bar over Menubar - macOS 10.15.6 + DisplayLink 5.2.4
 

Today, after updating macOS 10.15.6 and the DisplayLink 5.2.4 driver, my non-focused monitor now displays a white bar over the menu bar. Anyone else experiencing this?

Edit:
I found a solution, for anyone who stumbles upon this. I was able to toggle in an out of "Dark Mode" a few times, change my Display Setting > Arrangement, and Primary Monitor around. Eventually one combo of that fixed the problem, and I was able to return back to my default arrangement and dark mode.

Same here!
 

Found the same problem but couldn't make it work in dark mode by doing what you suggested. Light mode works fine and I'll add that the white bar will always be on screens that are not the default ones - meaning, whatever you drag the little white bar on the macOS display arrangement setting (which is the way you set your default screen) the other screens automatically will have white bars when mouse focus is not present and this only happens on macOS dark mode.
