Noticed the same thing, I made a thread about it a few days ago
Near Objective B (Insurgent side) on Farmhouse, there is this weird looking wall...
Not a bug per say, it just looks wrong.
This is near Objective D when playing as Security (after crossing through the water pipe).
All settings are at low.
If you equip the extended magazine with the L85A2, this happens...
It's mostly noticeable when looking down, but you can see a bit of it on top of your view when aiming down your sights with a 1x sight.
At the Security insertion point there is a graphics glitch with water (everything is set to low).
If you headshot someone and decapitate them, they sometimes still make a death sound. I would think this shouldn't be possible.
Just a minor thing.
