Possible lighting effect/abyss effect bug?

not sure what is going on with this but i'm not getting stuff like this on any other game:

https://gyazo.com/2d953bae007b0c21dd797cbbfb6c92ab - this was the first i had in maps and seemed to happen when i triggered an abyss rift thing, the grey covered were the tunnels went and sorta spazzed out when the hole came up.

anyone else having a simular issue? i'll try updating drivers after this lab run and see if it happens again regardless.

for reference in lab it happened in one of these rooms, pretty sure it was the one directly after the boss room however. - https://gyazo.com/7b76f28d9f76f8085043835f8e608c7f
