Dear Mathias!
Thanks a lot for the rapid answer!
Regarding the icons - yes, I can confirm, most of the icons I use have become suitable for FHD resolution. Only "Up" and "Eject" are old a little, causing they haven't enough pixels and don't fit good to the common modern display. We'll be waiting for the re-painting it in further updates
(check first prtscr please)
So why is DropDown Menu Font size 14px, isn't it too much? What was this value in previous 9.x version? All the other fonts are adjusted to 8px.
I wouldn't say I'm wanting to run MC as 100%. I would say, I wish to run it like MC 9.x
Please, check the second screenshot. Here are V10.1, V9.8XP, Win Explorer. They are just running all together to be able to compare the scaling.
So what I would say - here is a perfect fonts consistent in V9.8, and here is an evidence little issue with the DropDown Menu font size in V10.1. (And also the Command LIne Prompt font is larger than it was a little).
So I (and some other users I suppose) will really appreciate if You could manage fonts will be appeared as before, as in V9.8!
Also, I tried to run MC V10.1 with different DPI settings in Porperties, as You said. No matter, scaling and fonts appearing is always the same.
I didn't know that Beta testing is open for everybody, I could use it, if You'll suppose some of my reports could be useful.
Be awaiting for further fixes in further version! Thank You, Mathias!
