See screenshot; when I have NNW 7.1.2 in full-screen mode, there’s a featureless block that partly conceals the topmost item in the selected feed. As soon as I exit full-screen, it disappears, so that’s my workaround.
Issue persists through a restart; currently using Golden Gate public beta (26A5406e).
Thanks for the report!
It’s a macOS beta bug, unfortunately. John Brayton, author of the RSS reader Unread, has written it up and reported it to Apple: https://www.virtualsanity.com/202608/nstrackingseparatortoolbaritem-causes-white-bar-over-top-of-content-in-macos-27-developer-beta-5/
Hopefully they fix it before releasing macOS 27!
