Down at the bottom of the menu there's an altitude scale slider. It defaults to 1.2, changing it to 1.0 makes the trails look better.

It's amusing that changing the altitude scale doesn't reset the "trails" -- when I dragged it around quickly (on mobile) it left vertical streaks behind all the in-flight planes

I’ll fix that.
