Description Martin Tlustos 2021-05-04 08:58:48 UTC 
SUMMARY
When using libreoffice under wayland, antialiasing doesn't work, no matter what font I use. The same document works well under X. This affects text and menus alike.

ADDITIONAL INFORMATION

I use dark mode both in Plasma (Breeze-dark) and in Libreoffice.

Cannot reproduce with LibreOffice using the KDE/Qt backend. Are you using that, or the GNOME/GTK one?

Can you reproduce the issue with any other apps? How about Dolphin (KDE app) or Gedit (GNOME app?)?
Comment 2 Martin Tlustos 2021-05-05 05:14:15 UTC 
Upon further thought ;-) I remembered that I use the flatpak version from flathub:
Version: 7.1.2.2 / LibreOffice Community
Build ID: 8a45595d069ef5570103caea1b71cc9d82b2aae4
CPU threads: 4; OS: Linux 5.4; UI render: default; VCL: gtk3
Locale: de-AT (de_AT.UTF-8); UI: de-DE
Flatpak
Calc: threaded

which uses the gtk3 backend, so it probably is a bug with the flatpak. It's still funny that it works under X, but not under wayland...
Comment 3 Martin Tlustos 2021-05-05 05:20:44 UTC 
Ah, and all other apps (KDE, Gnome, flathub version of both as well) work.
Comment 4 David Edmundson 2021-05-05 07:02:54 UTC 
It probably loads things from xrdb under X.

There is nothing that indicates kwin is at fault.
Comment 5 David Edmundson 2021-05-05 07:21:24 UTC 
You can report to libre office and see where they load settings.
