I don't want to be that guy, but if I see you in my gym squatting like that, I'd come to you and just tell you "You gone get fucked up real bad, homie" (ghetto eastern-europe voice)
this is how a high bar squat should look like, more or less
also Lu Xiaojun. perfect high bar squat (ofc, we can't be as good as the best chinese lifter but we should strive for that)
I think your problem is weak quads and lack of tightness. You try to goodmorning the weight.
Start doing front squats - that's like the best thing you can do. Front squats and posterior chain work - all you need. It'll also teach you where your head should be, cause if you look down, you'll drop the bar.
