I've been running this now as my daily driver for a while and I haven't encountered any of these problems, other than the DSPManager. I have the Genius button as stock (I use Genius a lot), I did flash the non-paged app drawer and no recent apps, but I didn't flash the custom app background as I don't have a desire for it.
Phone: MyTouch 4G Slide (Black)
