#65927: M1 Black App Window Background for GTK Apps

--------------------+-----------------------------
 Just installed MacPorts 2.7.2 today (2022-10-03) on new Mac Studio (M1
 Max, 32 GB RAM) running macOS Monterey. Installed xorg-server using
 MacPorts. Ran the resulting XQuartz. Both GTK apps I have ported and
 tried, gnumeric and gedit, turn the body of application window black
 whenever the mouse is moved (both Apple mouse and non-Apple mouse). This
 is not the case for pure X apps, such as Xterm and xv. Both of these have
 no ill effect from mouse motion. From this I deduce that the issue is
 related to GTK. A fix would be greatly appreciated as all of the GTK apps
 I have tried are essentially not usable.
