My guess is that the jumps she is coming down onto are ones she isn’t seeing. I really can’t follow your “wings” and your “black” descriptions, but in general, it seems very clear to me she just isn’t seeing the ones you are having trouble with.
If there are certain jumps she isn’t seeing, and therefore isn’t jumping correctly, make sure you put some lighter/white in it for her to latch onto, visually.
Make sure there is a Ground Pole at the base of the jump. If she is taking off too early, its because she can’t see the base of the jump in that case, so give her a white striped base ground pole, set just in from where you want her to take off. Its just not fair to her not to give her these markers, because she clearly just can’t see them.
Its entirely possible that her eyesight is poor, but frankly, you have to realize that horses just don’t have good depth perception to begin with. For example, us Eventers, when jumping cross country out in timber, we walk the course to check out at the time of day we will be riding, where the shadows are for our jumps. Often, our horses can’t, or will heisitate, or run out suddenly, to jump INTO the shadow, from the sunlight, if a jump is in the shadow. But, they can jump out of the shadow, into the sunlight.
Its amazing that our horses jump so willingly for us, frankly.
Its clear your girl is game, and she jumps so boldly and obediently. I think she only crashes or runs out when she just can’t see.
Listen to her, and make the jumps so she can see them, such as riding right up to the base of the jump for her, for spreads, something you have to do anyway. She shouldn’t be taking off until you tell her to, so if she is taking off too early, you don’t have control of her take off.
Ride her into the base of the jump - that way she sees it, that way she is confident because you are telling her what to do, and that way she has enough scope to clear the oxer or debth of the jump.
Practice on smaller jumps so she gets confident of your signal to jump.
If you let her continue to choose her own take off point, and its too far back, you are going to have a horse start stopping and not being confident of its rider.
Give her ground poles at the base of the jump whenever you can. It helps her ride into the base of the jump, for spreads, and give her a bit of light on the poles she jumps so she can see them
If she crashing, she can’t see them, period. Ask her to wait and don’t take off early, and give her more light colors/white in the jump its self.
