I am using the "--enable-log="XXXX" --log-expanded " options, and on Gnome 3.14, I could resize the log window. In Gnome 3.22 this is no longer the case:
RHEL 7
yad-0.38.2-3.el7.x86_64
the command I am using is:
exec 4> >(sudo -u $user DBUS_SESSION_BUS_ADDRESS=$(grep -z DBUS_SESSION_BUS_ADDRESS /proc/$pid/environ | sed -e 's/DBUS_SESSION_BUS_ADDRESS=//') yad --on-top --no-focus --no-escape --window-icon="$yad_window_icon" --geometry=450x100-0+0 --progress --pulsate --enable-log="Update status" --log-expanded --title="$windowtitle" --image="$yad_image" --no-buttons --auto-close --text " Updates in progress.\n Please do not turn off your computer or close this \n window.\n\n While your computer is downloading updates,\n please be patient, as the download might take a while.\n")
