Description

This is on low quality, so no post processing in use. Anything using the MeshStandardMaterial seems to be affected.

This is on a Mali-G71

Research direction

Start by reproducing the darkened MeshStandardMaterial on a Mali-G71 with low quality and post-processing disabled, using the screenshots as the visual reference. The issue does not name a file, test, or entry point, so first locate the material and renderer paths handling Mali GPUs. Done means identifying and fixing the rendering discrepancy and verifying affected materials on the reported hardware.
