Worked: (newest version of Blender that worked as expected)
Short description of error
Let me show you an example of Rigging on bone text.
The text in viewport here is too small.
So I try to increase Theme > Text style > widget > points.
But it also creates overlapping blocks in the rest of the interface. This is problematic when they cannot be resized by command + two finger scroll (MMB), like in top bar menus.
Changing resolution doesn't work since the menus eat up a lot of space on the screen.
Exact steps for others to reproduce the error
See previous link https://developer.blender.org/T79059
Enable armature names in Object data properties.
Attempt to resize the name of the bone.
