Extremely small font in 4K resolution screen

With 4k resolution (3840 x 2160 pixel), The font in some windows is extremely small causing vision obstacle. Please see the pictures for details. Thanks.

which font scaling do you use?

if you use 200% no more issue?

Interesting. That solves the problem of Xnview, but make the global font in Win10 become smaller.

Since the 250% scale is the default option in Windows, I suggest optimizing Xnview to fit Win10 instead of doing it conversely.

Currently the QT librairies has problem with 150/250%

I am still using 250% scaling. The issue went away today itself. Weird.
