Yeah, I've had issues with DX10 as well, though for me it was always "zooming"; the outer borders are rendered off the screen. I guess I can fix it by adjusting my monitor settings, but then I would have to revert after quiting again.
TBH, if a game can't even render properly, imho it's not worth the effort (
Dawn of Discovery and
Clear Sky).
Bad news is, if you have an issue relating to DX10, there's nothing you can do but revert to DX9 (no biggie, really

). God knows I never found an answer.
