This appears to only happen during Windows XP testing. It looks like this code was rearranged in bug 1270650.

Comment 2

[Milan Sreckovic [:milan] (needinfo for best results)]

Right - Windows XP does not support DX11.  I'm not certain that we actually need this warning at all inside of gfxWindowsPlatform::GetAcceleratedCompositorBackends.

(Note this code already plays nicely with layers.allow-d3d9-fallback preference.)
