Its not blurry as much as for say like the sand storms and blizzards you would normally see with weather effects on and out in altepa or bec. glacier. When there is no weather there is no problem, the blurryness from the heat vents doesn't bother me and I learned to just ignore that while out there but this weather problem has been happening in altepa and in other areas of the game where we get earth, ice, and rain weather.
