Ok, it wasn't that.. the objects attached to the cursor were drawn after
the main screen contents, and there was no call to ghid_flush_triangles
after that point in the expose handler.
You can fix it quite easily. gui-output-events.c, in the
ghid_port_drawing_area_expose_event_cb function, after:
ghid_show_crosshair (TRUE);
ADD:
ghid_flush_triangles ();
Actually, this still produces mixed up colours a little.. you might like
to add:
ghid_flush_triangles ();
Before the call to:
glColor3f (cross_color.red / 65535.,
cross_color.green / 65535.,
cross_color.blue / 65535.);
in the ghid_show_crosshair function. (In the same file).
