Dopus 12 - funny checkerboard pattern in file path

I just upgraded to 12, and there's a sort of odd-looking checkerboard pattern in the file path above the file listing main window. (see attached image). I can't figure out how to fix it. Not a high-priority, because I don't think it's broken anything, but it's just annoying because it's also a bit larger than that space, so it's both ugly and distracting.

If it helps, it only seems to be showing up when the dopus app has focus - when the dopus window does not have focus, the display of the folder location looks normal.


Thanks

If you go to Preferences / Display / Colors and Fonts and change the Other Colors / File display border - Source, active, background color, then apply, does that fix things?

Default color on Windows 10 is 108,152,200

Adding image I meant to attach to previous post:


Yes, thanks! That fixes it. I just set it to the same as the inactive, 170 194 219.
