I noticed a performance regression with the new glutin code while running on Linux. I'm getting numbers that look like this:

New Windows: ~750 fps New Linux: ~50 fps Old Linux: ~250 fps

Same hardware for all of them. Windows 10 x64. Ubuntu 16.04 x64 with Nvidia 361.42 drivers.

Could be an issue with glutin maybe?

That sounds like vsync + some input loop delays causing frame drops on top. Although, I'm not sure, just speculating.
