Black canvas on ipad pro using latest version

Bugs
1

When I try to load a scene with SSS (PrePassRenderer) enabled on the latest version (Beta.4), the canvas turns completely black.
A demo playground:

If I change the version to 4.2.1 it renders but the SSS is somewhat messed up.

Device:
iPad Pro
Version: 15.2.1 (latest)

@sebavan - is that a known issue with iOS?

My iPad Pro 15.1 shows correctly in Chrome and Safari with the latest 5.0.
For 4.2.1 there is black-and-white mesh.

After upgrading to 15.2.1 I have the same results.

So it seems to be an isolated case on @Forsakenā€™s device?

@Forsaken, just to be sure, would you be able to try clearing cache completely and see if the results are different?

I have just tried, and the result is the same. @RaananW

Definitely on sadly enough, I did try changing some of the settings on safari but none of it really fixed it.

Here is iPhone8 Chrome screenshot (Safari has the same results)

I know this issue. It also happens on my IPhone SE 2020. It is because of the buggy WebGL 2 support in IOS.

Same here. iPad Pro M1.
Have noticed this on different projects already.
First thought it was because the texture size exceeded a limit?

Oh might be a M1 only issue ???
