Strange reflection on a ground texture in Korvan City

[Maska322]

Around the Korvan City, this particular ground texture has a strange reflection applied on it, making it look very shiny.

Furthermore, the shiny effect is based on camera angle. When I zoom in at maximum, the shine is gone or heavily reduced (although you can spot it on the top of the screenshot)

My video settings:

[Gnomish_Inquisition]

noticed it too in my game, no hdr on either

becomes extremely noticeable when rotating camera as the patch goes from like full shadow black, to normal, to gold/white shine
