Rain-X ?
had juddering wipers .. years back ..
1 .. i changed wiper brand ..
2 .. i stopped applying Rain-X to the screen
one or both stopped the juddering occurrences for good ..
( though .. i still add some rain-x screen wash premix .. now and again )
i stick to Bosch standard wipers now ..
( i.e. not the 'aero' type )
no probs. with them yet ..
~~~~~~~~~~~~~~~
EDIT ..
at some point i did have to replace linkage ..
maybe that had something to do with it ..
( as in .. don't know for sure .. )
plus .. i make sure the carwash don't spray wax on the windscreen ..

Works perfectly on a motorcycle visor, or any window that doesn't have a wiper. However on a wiped screen, Rain X makes the water bead after the blade has passed, which makes a smeary mess.
For smooth wiper operation, the screen needs to be free of all contaminants (silicone polish, diesel wax, Rain X), the wiper blades need to be at the correct angle to the glass, and the linkage needs minimal free play.
The blade needs to be exactly 90° to the glass when off the screen. This then allows the blade to flip to a trailing angle when the blade is in motion. If the blade doesn't trail, then it will hop over the glass surface as it wipes, which is what the judder actually is. It basically the blade hopping or jumping over the surface, as it moves.
