Ironically, I got to Entanglement stage today and have started to get this error:
err:d3d_surface:fb_copy_to_texture_direct Texture filtering not supported in direct blit
err:d3d_draw:blt_to_drawable Blitting surfaces from sysmem not supported yet
fixme:d3d_surface:fb_copy_to_texture_direct Doing a pixel by pixel copy from the framebuffer to a texture, expect major performance issues
