Correct.  It was mis-detected with my monitors so manual intervention
was necessary.  I hope you have better luck with the automagic stuff!

Sorry, I wasn't clear there.  I was referring to the minimize, maximize,
etc. icons in the window's title bar.  Not the ones you get from iconifying.

I use the 12x24 font on my 4K monitors.  Perhaps that will be close
enough for your size requirements.

I'm also a fan of the terminus fixed-width font.  On Debian you can
install the xfonts-terminus package.  It's available in 24 or 28 pixel
high versions (among others) through xfontsel.
