Knee subluxation

The reason I ask is because with a low-bar squat (powerlifting), I think it's generally accepted that you should go to parallel. With an olympic squat, ATG is easier to achieve. If you're having lower back back trouble, I'd try switching to a low-bar and stop at parallel but constantly concentrate on keeping your lower back arched and strong. Then if you feel it is getting better move back to high-bar if you want and try and build up to going ATG. This is what I've gone through recently and it's really starting to get better.

Lots of hip and leg mobility will help a load too.

This is quite a good exercise to do

But my back is fine. No soreness at all and feels strong. It's just on the lift phase I got a shooting pain though my knee so I'm wondering if my stance is wrong.

I'll try a much wider stance next time, shift the bar down my back further and concentrate on not going past parallel and see what happens.
