Texture issues with ELS vehicles and sirens going mute on 4 stars?

This texture issue happens when there are a few ELS vehicles close together. After it starts it doesn't go away until you restart the game. It happens everywhere on the map, its much worse when you're driving the road will become invisible. sorry for blurry quality that's vimeo not me.

The other issue im having is police sirens will go mute. It only seems to happen on a 4 star wanted level. Nothing fixes it except for restarting game. The click sound in menus also goes mute after the sirens go mute. The police cars that spawned before the glitch starts will still have a siren but any new ones that spawn wont. enabling the siren myself doesnt do anything its still mute. Not just ELS vehicles do this it happens to every vehicle with a siren. Video of the issue:
