### Godot version

4.0 beta 17

### System information

Windows 10

### Issue description

MultiMeshInstance2D is not displaying anything in renderer `gl_compatibility` (GLES3)
Works as expected with `forward_plus` 

### Steps to reproduce

Create a project with renderer `gl_compatibility`
Add a MultiMeshInstance2D


### Minimal reproduction project
