I currently cannot provide footage of this occurring due to software/Windows-related issues. But here is how to reproduce. 1. Find a wall that's with sloped ground by it. Hug that wall. Might not require a slope, but one is usually being stood on. 2. Use your Warlock Rift ability while moving toward that wall. One of two things can happen when the issue occurs. Either the Rift will appear way off of the ground that you're standing on (suspended in the air) or it won't appear at all despite using your class ability energy. It could be possible that the latter is just the Rift appearing at some unknown Y coordinate as well but I don't know if that means that it would appear above you all the time or if it can appear below you in the abyss. I've had this happen in the Crucible at a random wall in Burnout with a ceiling above me and in Cathedral of Dusk with a structure besides me that doesn't go too far up with no ceiling.
