I've read a little about this issue and have tried various things to fix my screen, like running into a spirit in a dungeon to go to the spirit world and then use the portal to come out of it. That worked. So did dieing and choosing to be resurrected (here). However, every time I have to zone, or travel using the map, the screen resets everything to dark blue as if I'm back in the spirit plane.
I put up with it for a long time, appreciating the moments where I could see and sometimes enjoying the challenge, but lately I haven't picked up the sticks and this is why.
Can someone help me fix this?
