I find that physics infused objects from Valkyrien Warfare tend to cause a full mono color screen occasionally for no notable cause or reason. No idea why this happens, but I only seem to get it when in the Misty World dimension. Only way to fix the bug is to break a block, upon which the screen will return to normal... for a while. Then it repeats again, sometimes only seconds apart. Not really something I couldn't live without, but it'd still be neat to build airships in the dimension :3

I use DrawBlockHighlightEvent to render fog. Perhaps the reason for this.
