Public bug reported:
Unity8's blur effect (such as in the app drawer) slows the system down
too much. I get 20 FPS with the blur, and 60 FPS+ without it.
Here's my unity8.log output (with MIR_CLIENT_PERF_REPORT=log) on a
6-year old laptop, rendering egltriangle before and after the app drawer
opens above it:

And while we still render the cursor manually this means the mouse
cursor also now moves at only 20 FPS.
