Just watch this.
I don’t ſee anything wrong (I aſſume you cut out ſome of the video). If you’re talking about the wingtip ﬅreaks, they only appear when your craft rotates ſlightly, which occurs when you move laterally.
They shouldn’t appear when the ship is not moving. In CI5 they don’t.
I think they appear because the ſhip is banked, due to the turning at the end of a level.
Will be fixed in next update.
