/sci/ I have a clear plastic screen protector which gets finger oils on it after use. I was just scrolling up and down and the multi-colored "oil blobs" (looks like gas on the ground with rings) - they move and combine and separate when I stop on a black/dark image before eventually settling. They even settle in roughly the same spot/way and only start to settle after I stop scrolling.

What is this? Is it the oils or the screen itself? I'm sober.
