Quality Issues Importing Custom Binder Icons

Hi there.

I’m currently using the beta version for Windows.

I’ve been trying to import custom binder icons in both PNG and ICO.
I’ve tested PNG with 40x40 and 90x90 and in both cases the icons become pixelated once imported.
I run a 4K display but it’s scaled at 250% and Scrivener itself and its base icons look sharp.

I’ve been reading the manual but that didn’t help.

Someone knows what I’m doing wrong?

Please save me, thank you.

As you say you are using the Beta version, you should have posted this in the Beta Testing forum.

Forgive me, I was foolish.
