"composite_state.get_compositor_transform(transform_index)" in composite_simple() seemed to affect to the problem.

With native compositor, negative scaling caused to disable external composite in TileCacheInstance::setup_compositor_surfaces_impl() on Windows. On Windows, negative scaling of external composite is not supported.

Similar thing is necessary for layer compositor.
