Attached file Small test case — 
Nightly has subpixel AA, OMTP doesn't.
Interestingly, this is specifically related to the pink background and the text here.
Sometimes we depend on the surface format to be R8G8B8X8 to enable subpixel AA. DrawTargetCapture never initialized the surface format, so sometimes we'd disable it.
