Both of the dx9 blitters are kinda "experimental" quality and don't support the OSD (such as pause icon, etc). Use the one which works best on your system. Kev is working on a new dx9 blitter which should be nothing short of amazing. I'm anxious to see how that turns out.
I will attempt again at fixing the rotation in the basic blitters when hw rotation is missing. The last two times I tried, I failed, so.. wish me luck!
