The official Rhino 6 for Mac release seems to have introduced some weird visual artifacts in the GH UI:
never noticed before… I’m running Version 6 (6.17.19236.01022, 2019-08-24)
That should be fixed in the 6.18 Service Release Candidate 1. Rhinoceros > Preferences > General > Update frequency and switch that to Service Release Candidates.
