I hadn't made any change. However, the default font does not seem to have been used. The font was probably changed in an earlier version. I can see the same behavior in v14 as well. I just hadn't noticed. Like I said, nothing important. After switching to "Segoe UI" it looks much better. However, there is one very small thing (see picture).
Wow, I couldn't have read the scaling factor from the support data. But this is really a very, very small blemish. And no longer annoying after changing the font to Segoe UI".
