[Freelancer (2003)] Odd-looking shadow appears when camera moves up/down (D3d8to9 only) #268

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.

D3d8to9 = 1:

I wonder if this is related to #136.

I'm not entirely sure since presumably the linked issue relates to legacy D3D8, whereas the shadow issue only occurs when converting D3D8 to 9.

I've created a PIX snapshot of the shadow bug while running the game with just d3d8to9 v1.12.0: ShadowBugFreelancerD3d9.zip. Thought it may give some insights into what could cause the bug to occur.
