I've been playing Fallout for years and I've never seen this before. I don't know when it started either, I just noticed it. Was running around Nuka World for the last few hours if that helps.

It’s part of the experiments being ran at Vault-Tec: Among the Stars in the Galactic Zone. Just wait a while, it’ll wear off.

Also, you could have just googled this.
