When opening the equipment dealer menu in the video game Freelancer (2003), the camera moves up before the interface appears. Whenever this is done with the D3d8to9 option enabled, an odd-looking shadow appears below the ship. If D3d8to9 is turned off, this doesn't occur.

I've tested this on DxWrapper versions 1.1.6900.22 and 1.1.6972.22; the problem could be seen on both.
