When I place a Lamp, or anything from Illumination, a graphical error occurs where a white phanton 2d shape appears on my screen and moves accross my screen in relation to where the lamp is to me. only happens at certain angles.

Edit: Occurs at all angles now.

Same error here. I should say, that optifine is not installed and the newest Project Red Version is installed. Here is part of the screenshot. The corners of the house are Lamps.

lamp rendering re-written. should be fixed.
