There's zero conflict if you take the extra steps as outlined in the FBlit docs, then icons are rendered in fastram instead. (This was a very common thing to do back when lots of people still used AGA.)
Anyhow, obviously don't do it if it causes problems, though it's always worked great for me.
*edit* Just to quote myself from the other day:
If you don't do the above, and choose "other memory" in WB prefs, you will get the nasty lines when opening drawers. Otherwise it should work fine - there will be a little speedup when opening drawers (icons are displayed faster), and icons will use very little chipram.
Hiya,
But doesn't Fblit work by copying everything that needs to be rendered to FASTRAM and then blitting to CHIPRAM only what needs to be redrawn each time? If that is the case, it would make no-sense (eg no performance increase) to make another copy of your icons in FASTRAM.
