Alpha 13 iOS Shader Issues

I upgraded to the alpha 13 to see if this bug was fixed (it was introduced in 2021.2.1). When I build to iOS, there are a lot of graphical issues.

Here is just one example. This is a particle system trail module. It seems most of the issues have to do with transparency.

As you can see, the trail is shorter (I am assuming it is transparent) and not colored correctly.


Is this a known issue?

EDIT: It seems like when something is instantiated it happens. That trails is created on start and also all the other similar issues the sprites are created.

Case #: 1380175

Yeah they also introduced this bug in 2021.1.28 all my shaders look funny. Most of them are particle system shaders. To be more specific this is a new bug that requires you to run it on the iPhone. On the editor it looks fine. I checked 2021.2 and the alpha and they all have the same bug.

2021.1.27 seems to be the last stable version without this problem.

For reproducing turn on the light theme in device settings. Works correctly in the dark theme
