bullet, you will indeed be making another glass render in the very near future because I will force you to do so until it comes out perfect
It bleeds like water because you need to turn the color gain of the IBL down.
Are you sure that second render is three point lighting? Because it looks like IBL to me as well, it's got those very distinct patches on the floor plane that comes from not having the final gather settings high enough with certain probes.
But not to worry, a week from now I will have nagged you enough for there to be a perfect glass render instead
