It's not that this is only a problem with swap_interval == 0. Even with 1 (i.e. without '-n'), we seem to be rendering at 67fps on _some_devices_ (wink, wink ...) when overlays are enabled. (Changed the title to more accurately reflect that.)
It may be a more fundamental problem in our rendering logic, so bumping priority back to high.
