On the left is a shot from editor and right from WebGl build.
We use gamma color space for lower webgl apis to work and Crunch compress to make builds smaller. We also use low quality URP asset and all materials in shots are with Sprite default unlit material. Problem occured when moving from 2019.4 to 2021.1. UI images are not effected at all so I guess it is somehow light issue even with unlit material and shader.

This occurs only on WebGL build.

Switch code optimisation from “Size” to “Speed”. It’s been broken for over a year now in every version since 2021.1…
