Environment overrides causes fireflies

[Michał Morzy]

Hi guys,

Do you know why when I use some HDRI as as an environment override it causes the fireflies/white empty pixels? It isn't only one scene. I happens almost everytime I want to override the visiblity map for slightly different set-up hdri.
