NFS4 dashboard blinks in rainbow colors

[Hommelwomb]

I have downloaded following car: https://www.nfsaddons.com/downloads/nfshs/cars/jaguar/2829/jaguar-jaguar-xj220.html

In game I realized that the side mirrors of the dashboard view are misplaced - flying in the air.

So I moved them using FCEFIN2 to the correct position.

But now in game the dashboard starts flickering in raindbow colors while driving in sun light.

Anyone know why?
