<r> Request for the AIM-9X Block II+ that appears to have some sort of improvements to make it more stealthy (RAM coating maybe?) so they can be carried on the F-35 externally without compromising that much the aircraft radar signature. Im not yet able to post the source link as I don't have enough ...

Any update on this? I've just tested it again and it still happens the same.

I've made this simple scenario of 4 F-35 vs 4 J-20 with nothing else, sometimes no missile overshoots, sometimes one, two or even half of them overshoot one time. Usually the ones to overshoot are the ones that are fired first.
