Hi,
Not sure if this is on the radar but ever since the usertext panel was introduced it does not work well with more than “a few” usertexts.
Check this video representing a typical model we have.
2K + objects with around 100 usertexts
Whenever the usertext panel is active selecting many objects freezes Rhino until the panel is populated.
The panel is re-populated after a move, again freezing Rhino.
