Comment 1 for bug 1350725

Just re-tested this, and while still true, discovered a problem.

My high-end quad-core i7 system can't keep up with compositing if I throw 10+ triangles at it use enable double-buffering. It requires the display buffer to remain triple buffered to keep up. Sounds like we need to work on the efficiency of our compositing before it's feasible to resolve this bug, if ever.
