Currently, the overlay when hovering a region in the tiled view is done by creating individual instances of Rectangle. It works fine for small regions, but scales poorly when hovering a large free zone (I've seen the computation time shoot up to 150ms).
I don't think there's a magical property that can help, so the best is probably to do the rendering manually, like for the regions.
