no high-DPI scaling for some applications?

Hi there!

I've setup a kali-linux xfce desktop (via Windows10 wsl2 + win-kex package) and to get it looking crisp I set it up so that Windows doesn't apply any scaling to it, but rather make XFCE do that itself. (see also: https://www.reddit.com/r/Kalilinux/comments/14iicps/winkex_windows10_highdpi_setup/ )

I'm mostly happy with how that turned out, but now those two applications look much too tiny:

LibreOffice
unison-gtk

How can I get XFCE to apply high-DPI scaling to those too?

If you have set the XFCE scaling and GDK scaling up (to 1.5 or 2 ) you can choose or download a other UI Pack for Libreoffice. Libreoffice support themes that will better match for High-DPI https://wiki.archlinux.org/title/LibreOffice#Theme. For the application unison-gtk I have no idea.

Hope that helps a little bit.

  It seems Kali linux's LibreOffice packages already come with svg icon themes installed out of the box:
  
  ls /usr/share/libreoffice/share/config/*svg* images_colibre_dark_svg.zip images_colibre_svg.zip
  
  But somehow that setup is broken. I managed to solve my issue with LibreOffice by uninstalling all LibreOffice related packages from the Kali Linux repositories and instead downloading 7.4.7.2 Linux_x86-64_deb.tar.gz from https://www.libreoffice.org/download/download/ and installing all the *.deb packages it contained.
  
  But sadly, even though I've solved this one, the list of applications I'm missing HighDPI scaling on has grown:
  
  unison-gtk
  
  bless
  
  emacs
  
  If you or anybody else has any hints on what I could try to improve my situation with one of those, I'd love to give it a go! :)
Now I found a solution that works for all the apps I tried so far:

add export GDK_DPI_SCALE=0.5 to /usr/lib/win-kex/xstartup

activate "Settings Manager" -> Appearance -> Fonts -> DPI -> "Custom DPI Setting" (leaving the proposed 192 next to the checkbox)

restart XFCE desktop session, and remove all the env QT_SCALE_FACTOR=2 prefixes I've previously applied to various QT-app shortcuts to prevent double scaling.
