Shipment ground flickering after season 3

Downloaded the update today and started playing on the small map moshpit in order to level up and get the camos for the mp9. Played on all the maps from the playlist and after playing one Game on shipment, saw that in all 4 corners of the map the floor texture was flickering. Restarted the shader preload, same problem. The rest of the maps are ok, only shipment is affected. Before the update the floor was ok. Has anyone else noticed this?
