Pink thread post background?

So I made a thread in video games, and... well, look.



I thought Jacob updated it or something, but when I looked at other threads they were all still white.
I went back to the one I made, now it was white.

What was that about?

When you make a post. Or click to view a certain posts he seems to now highlight this.

I think this is relevant to this
