There's a small subset of systems experiencing this. Do you happen to have a Radeon video card? In the profile I looked at, glClear was calling down into (through libxcb) __poll_nocancel which was eating 99% of the CPU time. I'm not sure if there's an issue open for this yet, but it's something we're looking into. One of my testers during development ran into this so we're aware of the problem.
