Lexus RX 2010-15 :: Wiper Leaving 3 Distinct Lines Across The Screen

So my drivers side wiper is leaving 3 distinct lines across the screen. It sort of looks like something is being dragged across the screen in the rain even though the wipers are clean.

Like this (except only 3 lines):

Anyway, I changed the wiper refill on the driver's side regardless but it still does the same thing. What it could be? Its not the refills as they are brand new.

Another thing - I used RainX and the wipers have removed it where the 3 lines are (which is why they are showing up as lines).

The 3 lines are exactly where the clips for the OEM plastic housing is which hold the rubber refill.
