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

Since I upgraded to Ubuntu 21.10, some UI parts are displayed with black text on black background in LibreOffice 7.2.1.2, making them unreadable.

This is the case in particular for sheet names in Calc:

Unreadable sheet name

I can't find a way to fix it...

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

Workarounds are:

  1. use another theme alltogether

  2. 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).
