Previously, we would use a single offscreen framebuffer for both transformations and when a shadow framebuffer should be used, but that can be dreadfully slow when using software rendering with a discrete GPU due to bandwidth limitations. Keep the offscreen framebuffer for transformations only and add another intermediate shadow framebuffer used as a copy of the onscreen framebuffer. https://gitlab.gnome.org/GNOME/mutter/merge_requests/877
