Graphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 440.82
Broken: version: 2.83 (sub 17), branch: blender-v2.83-release, hash: rB1d2b89304ac3
Short description of error
In the viewport or render the result I get is different from 2.82 and 2.83. If I remove the HDR image from the world nodetree, the issue seems to disappear.
Note: Because of another bug (T73131?) you need to save and re-open the file to be sure the results are still different.
