To start painting, call: gui$get_window_backing_store() Then finish up with: gui$release_window_backing_store() Process will retain the underlying GraphicsBitmap behind the scenes. This fixes racing between the WindowServer and GUI clients. This patch also adds a WSWindowLocker that is exactly what it sounds like.
