Which game are you talking about?

A similar sounding issue occurs intermittently in the vanilla game if you quickly pan the camera between underwater and above water, i.e. the cubemap reflections become fully opaque. Not sure whether it could be related.

What do you mean redirects? Are you at http://enbdev.com/download.html or somewhere else?

Firefox was updated last night and it seems fine here too now. An odd issue indeed but whatever, at least it's gone now.

Which browser are you using? I'm using Firefox and experiencing the same issue but reloading the page for a few times seems to help.

In any case it's not related to you installing ENBSeries at all.

Try disabling full-screen optimizations in the executable properties.

Try Download > TES Skyrim SE > v0.475 > scroll all the way down and click the arrow with the text “download” next to it.

No worries, glad to be of help.

Try decreasing [WINDOWLIGHT] intensity.

What was the culprit?
