GTK_THEME=Adwaita abiword from a terminal. If that works,
GTK_THEME=Adwaita:dark abiword and see if you like that better.
Você pode criar um .desktop
arquivo e isso permitirá que você clique duas vezes no ícone Abiword ou em um arquivo Abiword para abri-lo com o tema Adwaita:
Salve-o como ~/.local/share/applications/abiword.desktop
