Vocabulary question for native english speakers

[Zero01]

I like 'shinmering' as suggested above. Although if I were to try to elucidate what I'm actually seeing in the picture I would suggest 'granular haze', not a single word unfortunately, but you could invent a new compound word: 'granular-haze' ..!
Reminds me somewhat of a 'heat haze' coming off the ground on a hot day.. but the pixelation is reminiscent of a grainy texture.
Or shimmering, maybe.
