As i was checking out the new vibrant visuals on the lowest settings, i saw these weird stripes on this mountain.
The sun was currently going down. Between the shadow and the sun was another hill with a tree ontop, however there was no structure or blocks there that would produce these stripe shadows. When i went into the settings screen they dissapeared until i got back out.
Environment
In a Jungle when the sun was going down.
