VLC text tiny on 4k display

[mr-b]

Hi

I'm having some odd text scalling issues with VLC 3.0.12.1 on a 4k display using 175% scaling.
It used to be fine, but I had to reinstall a display driver, and had to reset the scaling back to 175%.
During that time VLC has somehow got messed up and now displays tiny (virtually unreadable) text in some menu options.

I've tried resetting prefs, reinstalling, deleting prefs, installing nightly but I can't get the old scaling back.

How can I fix this, as VLC is virtually unusable now?

E2A after seeing recommendations in other threads to downgrade (but that don't ref text) I've found that none of the 3.x versions fix the issue, I have to go back to 2.2.8.

I saw that thread but it concerned the buttons. Also adding the environment variable made the buttons bigger and everything else look weird - scaling and spacing was really off.

Then I dug around in the app properties, enabled High DPI scaling override and set scaling to be performed by System. This rstores the legibility of some of the app text but then the app is blurry.

Then I tried disabling that and instead enabling Program DPI, and set the option to when 'I signed in to Windows'.
And that works! The app isn't blurry and text is now readable.

Is there a bug filed for this?

Hmm, the file select dialogue box is still using tiny icons and text so this workaround isn't 100%.
I found several DPI-related bugs on trac but they last had dev activity 3y ago, so not very promising.
Unfortunately I don't know enough about DPI settings on Windows to pinpoint the issue.

Remove the checkmark from "Resize interface to video size". The setting is shown in your screenshot.

That setting only changes the VLC window size to match the video's size, and doesn't appear to affect DPI text/icon sizes.
