Water not updating/taking a long time to update. Saving in this state can cause massive stutters when relaunching

Sometimes water will not update. It seems fairly inconsistent to trigger but when it happens it can persist for minutes at a time. Normally it resolves itself after a few seconds but I had one save that was stuck in that state for 10+ minutes, on reloading that world I was hit with massive stuttering that caused the game to drop to 0 fps every few seconds and this persisted to other worlds. It was fixed by relaunching the game. Sometimes this stuttering only lasts a few seconds and resolves itself.

I have a video of this in action but its too large to upload. If youtube links are allowed let me know and I can attach one.
