LibreOffice has some black on black UI components, making them unreadable (since upgrade to 21.10)

THe problem is due to the Materia-compact Gnome Theme used:

Workarounds are:
use another theme alltogether
use another theme for LibreOffice only:
GTK_THEME="Adwaita" find /usr/share/applications -name libreoffice* | xargs -i cp {} ~/.local/share/applications find ~/.local/share/applications -name libreoffice* | xargs sed -i "s/Exec=/Exec=env GTK_THEME=$GTK_THEME /g"
Now, LibreOffice uses adwaita theme (but the window title bar still uses materia-compact, so it does not feel weird).
