Vulkan Mobile: Renderer not displaying 3D since 4.0.alpha10

[ViktorEvil]

Godot version

4.0 alpha 10

System information

MacOS 12.4, Apple Silicon M1

Issue description

Godot 4 alpha 10 fails to display any 3D object in the view port if the Vulkan Mobile renderer is selected.

Alpha 10

Alpha 9

Alpha 10 interface is also extremely laggy and stalls with a beachball until force quit. If I create a project using the Vulkan Desktop renderer the 3D view port displays correctly.

thousands of errors as above using the mobile renderer

Steps to reproduce

create a project in Godot 4 alpha 10 and select the mobile renderer

Alpha 10 interface is also extremely laggy

This is caused by the large amount of error messages being printed to the editor's Output panel.

Duplicate of #61817? If so it should be fixed in master.

Yeah, Will need confirmation from someone on a Mac, but it indeed looks exactly the same as #61817 (same shader logs as what bruvzg posted. If so, should be fixed by #62305

I've been using the mobile renderer for a 3d project on macOS on 4.0.beta2 to beta8 builds and have not seen this problem. So I think this can be closed unless @ViktorEvil is still experiencing these problems?

[akien-mga]

Thanks, let's close. Please comment if you can still reproduce this issue in the latest beta.

Just tried mobile renderer on beta8 and it’s fine
