Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2080 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.59

Blender Version
Broken: version: 3.2.0
Worked: version: 3.1.2
Caused by ca37654b63

Short description of error
Bloom Pass output of Render Layer compositing node outputs the final combined image, and not the expected bloom only pass.

Exact steps for others to reproduce the error
1 - Open default scene
2 - Enable Bloom in Render Properties (values of bloom do not matter)
3 - Enable Bloom Pass in View Layer Properties
4 - Render and check pass

Default Light set to Sun for ease of viewing, light setting does not impact this issue.

File with these steps followed included:

I reconfirm that the mentioned commit is the culprit. Will review the change perhaps it changes the gpu state in a way that wasn't meant to be.

Issue is that the order of uniforms are reversed and an additional uniform overwrite the bloomAddBase to include the render result.

(Left is incorrect, right is correct)

(call overrides the previous value...)
