In depth

The tile the current frame is sampling is never evicted. That is the one rule this structure exists to enforce: an eviction policy that can reclaim a tile in use produces a frame drawn against a page somebody else is writing, which is a corruption rather than a stall and does not look like a streaming problem at all.
