I was using tessellation on my warlock doing the Shadowkeep quest. I wanted to use the pre order weapon for the final shape. This seems to be an armor glitch with the warlock Dreambane chest piece specifically. As you can see with the image on my twitter it covers the entire screen ADS'ing it's wild. As soon as I switched off that chest piece to a different one it worked normal and I could see. Just wanted to bring this to the forums so it could be addressed! All in all awesome freaking weapon bungie.
