Automatic migration. Original reporter: "_2b"
the d3d9renderer uses only one texture stage and sets all states for stage 0, but does not disable stage 1. so when the main programm does some rendering and uses other stages, cegui-rendering my fail. this may also apply for the d3d8renderer.
to securely disable texture stage 1, use SetTextureStageState(D3DTSS_COLOROP, D3DTOP_DISABLE) and SetTexture(1, 0);
a patch is attached.
