### Tested versions

Reproducible in: 4.2.1 - RC1
Not reproducible in: 4.2

### System information

Windows 11 - Godot 4.2 - Compatibility

### Issue description

When using a GPUParticles2D in Godot 4.2.1-RC1 no particles are rendered on screen

### Steps to reproduce

Create a project using 4.2.1-RC1
Set the rending mode to Compatibility.
Create a GPUParticles2D system.
No particles are rendered.
