Screenshot of bluetooth widget with thick divider
The divider line in the network and bluetooth widget has become a thick rectangle with this version of Plasma. I'm assuming that because it is so in both that it is a more general Plasma issue. (It may also just be a problem that these widgets have in common.)
KDE Plasma Version: 5.23.4
KDE Frameworks Version: 5.88.0
Qt Version: 5.15.2
Fixed forever in Frameworks 5.89, thank goodness!
