Strange issue with text panel font size

I have two machines that share same second screen and same external storage. Both have a text screen scaled 150%.
Machine No1 panel text font size is: 8, 10, 12, 20, 30, 40
Machine No2 text displays text size at: 9.3, 11.2, 14, 23.3, 35, 46.6
Same file loaded from external storage, different behaviour. What is happening and how to deal with it?

I’m not sure if I understand the problem correctly. Can you share an example file and _SystemInfo for both computers?

Not anytime soon, I will not be around my machine No2 for a while but I will try to illustrate it:

Setup No1: MBP (bootcamp) Win10, Rh7 + 26" Acer 4K display + external storage
This text is displayed 20pt

Setup No2: ThinkPad Win11, Rh7 + same display + same external storage
This text will be displayed 23.3pt
All text sizes will grow respectively (as per first post)

Note: Gh file is loaded from external disc , Grasshopper is always working on a secondary (Acer) display
PS That second setup text size is wrong.
