Steps to reproduce:

1. Open the attached project
2. Open "Hotel_Beach" scene
3. Look at the plane before playing (look at the screenshots)
4. Press play
5. Look at the plane again, you can see that the artefacts of UV maps appear on the plane

Note: Disabling static batching will not reproduce this issue anymore

Expected behavior: Artefacts of UV maps are not appearing when static batching is turned on

Reproduced on: 5.4.2p1, 5.4.1f1, 5.4.0f3

Note: Couldn't reproduce this issue on 5.5 due to a lot of script errors
