Have you checked how long this runs for? It's not really a unit test (it doesn't
really have a way to fail - it just prints timing information). If it takes more
than, say, 10s, let's keep it in a separate binary, to avoid taking time on
bots.

Looks like 30s. Made it a separate binary: display_compositor_benchmark
