Portal 2 weird lighting bug [Fixed]

Edit:It's a HDR lighting error. I was using _vertex textures on the walls. It's good now.

So I made a very small map and this appeared. The lighting I have in the maps are normal "light" entities and a observationroom instance. Similar effect all over the map.

I would like to know what this is and how I can avoid it.

Low quality video due to me recording this in 800x600 windowed. Doesn't really matter though.

@BaillieMinecraft You're right. I did ask the steam forums. This was used to describe it to them.

Should say it was fixed in the title now.

It's because you're using the _vertex textures, I think.
