Weird visual issue in UEFN with brown lines

Summary

Im unsure what this is but at first i thought my monitor was broken but it turns out i have some weird lines in the editor but only when look at certain things. When looking at the sky for example the lines and invisible but when looking at the landscape they show. They also seem to be in a state of animation like they are faint then get stronger then faint again.
