Details

When we don't integrate with the OS compositor, there's extra memory and bandwidth overhead from first rendering into a tile and then compositing it.

In this configuration, If a tile is continuously invalidated we would be better off rendering it into the framebuffer directly.
One way to do this is to disable the picture cache slice entirely when we think that caching is costing more than it helps, another way is to do this per-tile, allowing some of the tiles to be cached and other tiles to be rendered directly into the framebuffer.

Priority: -- → P3

There is only picture caching now, I don't think we intend to do anything here.
