It's in the manual.

B.4.5 Does preview-latex work with presentation classes?

preview-latex should work with most presentation classes. However, since
those classes often have macros or pseudo environments encompassing a
complete slide, you will need to use the customization facilities of
preview.sty to tell it how to resolve this, whether you want no
previews, previews of whole slides or previews of inner material.
