Is it bug that certain textures (which are not the following: black25-75, blank, gray25-75, red, white, whiteCheck) started to get a weird tinge on them?
Exhibit A:
From a distance a red artefact can be seen on the siren texture.
Exhibit B:
From a distance a green artefact can be seen on the round turn signal.
These are not the only vehicles affected by that, and back in v19 or even during the first few releases of v20 I had no such problem with the textures.
