foliage doesnt stay down like it should be from far away

I’m trying to replicate a landslide. I want my trees to be at a angle. But the trees stand up when camera is far away. It wouldn’t be an issue if it was just that. But when rendering a video (of a camera moving trough the landslide, not animated) the trees are upright until the camera gets near the trees.
I hope the following images are uploading correctly. the two images show the same trees, two different distance from the trees.
