Tab names display random characters

Problem is solved ! I was using SEGOE (which is standard for Windows 10…) and change it to ARIAL just to see, and it’s working. So it must be an issue with SEGOE font. Thanks for all the help. Still, I wish it worked with the standard font, I’ll have to make myself to the new one.

I do not think it is Segoe itself - I have this also on my test machine. Do you remember by chance if it was Segoe Variable?

It was written “Segoe UI”, can’t remember of any “Variable” thing. Tried it also with Helvetica and it’s working great. I’ve used a .reg file to change the system font.
