In zones with fog effect (Rusty Ruin, Diamond Dust and Volcano Valley) having VDP2 NBG2 enabled causes VDP2 NBG0 layer transparent.
After beating a zone of this type, some graphical corruption remains in the next zone if it is a no-fog one. This glitch makes VDP2 NBG0 layer transparent where both layers overlap. This behaviour only finishes when you enter a special stage.
