Switch between D3D9 and D3D10/11. I get those when I have D3D9 enabled, but switching to D3D11, it removes it for some reasons.
I actually only needed to know if this is some new bug or something known.
I can't switch to DX10/11 because I'm on XP and with card that support DX9 only.
Those lines doesn't exist in DX11 mode. At least from what I experienced. I guess it only happens with DX9?
Oh and, the game needs Alpha Stencil hack in some battles with flickering shadows.
