Shadows on trees?

[banned]

I had a fly tonight and came across a 109 coming towards me. I turned in behind him and saw him diving to the deck. The next thing I see is he is flying through the trees.
I kept above the tree line waiting for him to pop up. He just kept flying through those trees until he built up enough speed to exit and outclimb me.
His mate came in and filled me full of holes, which didn't bother me. I manged to land in a field.
The advice I got was 'turn off the trees'. It annoys me that I have to turn off the basics of the game to stop these buggers cheating. It sucks.
I hope, one day, they do something about this. It ruins the whole feel of the game when things like this happen.
