Is there a graphic glitch on the tunnels?

I notice when cycling through the tunnel on Ocean Boulevard that there is a straight section of empty water visible above the tunnel (ie, no water, just sky visible). It runs down your left when you enter the tunnel (forward direction) and straight across where the tunnels curves left and bends back around to the right. There is no apparent reason for this. Is it a graphic glitch for me, or do others see it too?

Steven, I’m not sure I’ve seen anything like that.  Next time you see it could you take a screenshot and post it here?

Hi Jon

 

Attached are 4 screenshots, plus a grab from the map with marks where I took the screenshots. They are loaded in order… I have also drawn a red line where the glitch appears to be. It seems like a straight line to me.

 



Hi Jon - anything further on why I am seeing this?
