Greetings to the Community!
It's been a few days since I haven't seen (they have become "microscopic") more icons in the structure panel (not a big problem, but it's annoying), does anyone know why and how to solve?

You don't use Master. Does it occur as well if you use a precompiled package?

I apologize for the delay in answering (but I tried and tried again for the curiosity to get to the cause of the problem), the problem occurred on the FreeCAD-asm3-Daily-Win64-Py3-Qt5-20210501 standalone distribution and on the previous one. In the end I uninstalled that version and installed the FreeCAD-asm3-Daily-Win64-Py3-Qt5-20210504 (always standalone) (clean installation also deleting the configuration file) the problem, at the moment, seems solved. If it happens again I will propose the thread again.
Chrisb thanks anyway for your interest (you are always a great resource!)
