### Tested versions

Reproductible in 4.2 stable
Not reproductible in 4.1.3 stable

### System information

Godot v4.2.stable - Windows 10.0.19045 - Vulkan (Mobile) - dedicated NVIDIA GeForce GTX 650 Ti (NVIDIA; 30.0.14.7444) - AMD Ryzen 5 3600 6-Core Processor (12 Threads)

### Issue description

Reflection probes simply don't work on Vulkan mobile and Compatibility renderer.

### Steps to reproduce

1. Create a sphere with a metallic material with low roughness.
2. Create some geometry to reflect off of the sphere
3. Add a reflection probe to the scene
