Header and Footer text in eBook Viewer Illegible on 4k monitor

[Joe Blow]

The header and footer text are toooooo small on a 4k monitor, they are unreadable/unusable.

Here's a screenshot:

The eBook reader needs an option to independently set the font face and size for the header and footer.

Currently using Calibre v7.24 x64 on Win10.

Thanks

The font size is the same as the font size for the rest of the calibre
User Interface. You can change it under Preferences->Look & feel->Main
interface in calibre.

And the default value works fine on my 4K monitor in windows, something
unusual about your setup?

In particular, do you have multiple monitors with different DPI, from
your screenshot it looks like the effective font size is being
calculated for a different DPI than the DPI of the monitor the window is
on.

Yes, I have multiple monitors. Primary is a Surface Pro 8 13" 2880x1920, and the secondary is a Dell 27" 2560x1440.

Nevertheless, changing the font size for the main interface isn't going to be a workable solution, as the main interface is displaying perfectly with correctly scaled fonts on both displays, no issues at all there. Scaling it's font way up to make the reader's footer font legible will just make the main interface way too big and unusable there.

The only thing with an issue is the header and footer in the eBook viewer, everything else is displaying properly.

So either there's a bug in the eBook viewer causing the header/footer fonts to be scaled incorrectly, or it just needs an option to manually set the font for the viewer independent of anything else.

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.

Super, thank you very much!
