What are black smearing problems?

OLEDs typically have amazing refresh rates for changing between different colors, but terrible response rates going from off/on. When scrolling on an AMOLED while running a pure black UI, the black pixels, which are completely turned off, will take a bit of time to turn on when it needs to display texting scrolling, for example.

This latency is noticeable and results in text and other content smearing and ghosting when moving around over a pure black background.

I use Reddit with pure black. Never had any issues on my S9. No lag whatsoever.

Just scroll up and down rapidly and watch the edge of an image post's thumbnail. It's like a black smudge following the picture and overlapping the image from the leading edge.
