Using detail maps on a lit material while having the scene fog set to linear will result in bad rendering artifacts. The artifacts are different depending on the baked GI mode.
Steps to repro:
# Open the attached project
# Build to android

Expected: The build looks like the scene view

Actual: rendering artifacts

The artifacts are different per light mode (remember to rebake when testing the different modes). I've attached images of each:

Baked GI disabled: Reflections look incorrect
Baked indirect: grey noise in depth
Subtractive: flashing and everything is in 100% fog
Shadowmask: flickering and nans and stuff
