I've seen this a bunch on the forum the last few months. It only last a second or two but I finally was able to screenshot it. It looks like a little glitch or photo refresh, but it's always specific to only one file. It's like an algo getting it and doing some kind of manipulation, etc. Don't know enough about these types of things to say, but its the only page that I visit that does this.
