KDE with disabled compositor, i3, etc. use alpha visual, but it's not transparent.
Could -moz-gtk-csd-transparent-background be defined with gdk_screen_is_composited()
and be used to forbid outer border-radius + outer shadow of main menu/addon/etc. widgets
to remove any Xshape usage (bug 1730991 comment 6)?
According to the Chromium bugtracker, Xshape also causes performance problems (bug 1730991 comment 7).
