Again, does the problem disappear if you don’t have any popups in your UI. (The
answer was no, not completely, before.) If there’s something going on *besides*
the way popups are drawn, you shouldn’t get too fixated on those.
OTOH, before you go to too much more trouble with this, it seems to me that
your next step is to convert to a view-based table view. It’s really not that
much work, and cell-based table views were deprecated in 10.10, which is
basically 3 years ago.
If you have to submit a bug report, I think you’ll get a better outcome if
you’re not complaining about a long-deprecated feature.
