----------------------+--------------------
 Whatever I tries to set (eg:GTK_THEME=Adwaita:dark zenity --calendar) the
 windows created by zenity on my local machine or in X11 from a remote
 server appear white on white.

 They are functional as I can for instance click the invisible OK button in
 the calendar but text and items are all pained in white.

 zenity:3.42.1 (macport)
 osX: 15.1
 XQuartz 2.8.5 (xorg-server 21.1.6)
