Floating distant scenery

[SAR704]

I was just having a little glance at some scenery I added tonight, and I noticed that some gum trees (placed through asset blocks) seem to look as though they're floating in the air from a distance, yet they look normal close up.

I have noticed this with TS previously, but this just looks way out of order, considering it's the line terminus.

Here's some visual evidence of this.

With a few hundred metres:

From the yard:

Has anyone else experienced this and found a workaround?
