I was recording a gif for my game and I noticed a grayscale kind of thing that kept showing up. I wanted to ask why that happens, because I noticed a pattern with it when I was walking between rooms. The corners are always full, but the tiles that change between rooms are either grayscale or full.

(The pattern shows after I go into the menu)
What is the process that causes this to happen? And is there a way to fix it? Because it is kind of distracting.

For whatever reason, mine also does this:

Could be a problem with the recording software/ framerate on JusTIfied.

That used to happen to me as well but it suddenly stopped one day.

Probably a bug with the animated capture feature. I don't think this bug is a feature.

It's a bug in how the LCD physics in jsTIfied (the emulator in SourceCoder) interacts with animated GIF recordings. I've been meaning to look at it for years, but time is short. But I'm also happy to accept DJ Omnimaga's explanation of it as a feature.
