I'm not sure what you mean,my icons are not see-through, however they may just appear like that either because its not an actual screen shot and rather a picture or my HD2's flash might also be the reason.
I do see that some apps like MobiTv and the new youtube app are some what see through if that is what you mean.
other than that I remember posting a zip file on this forum with some of my wall papers for my start menu and lock screens, and or also Im running NRGZ28's Energy rom 23xxx series build with Cookie on my TP2.
EDIT here is a shot of my Start menu screen for clarification.
