> Under the conditions specified below, new graphical frames are
> completely white until a redrawing is forced (usually by resizing the
> frame):
>
> Emacs built with:
>
> - No toolkit OR Lucid (--with-x-toolkit=no OR --with-x-toolkit=lucid)
> - Cairo (--with-cairo)
> - Double buffering (--with-xdbe)
>
> Plus:
>
> - Without an X window manager OR using TinyWM
> - No toolkit builds: when scrollbar is disabled before creating the frame
> - Lucid builds: when scrollbar AND menubar are disabled before
> creating the frame
>
> Affects `emacs -Q'.  Tested on Debian GNU/Linux 12.1 (Bookworm).
