I don't really see how the frame rate could have been higher than the refresh rate if vsync was enabled unless there was a bug in the vsync code in older kernels.
I'm not an expert like you, but I think that the fps is going from 120 to 60 and that should be possible as 120 is multiple of 60 (my refresh rate). Is this correct? If you need, I can bisect in some days.
