I _guess_ it's ATSUI, a text rendering engine build into MacOS (at least I think ATSUI is this, maybe I understood something wrong).

Some time ago, there was a Pepper version that supported ATSUI (Maartens Pepper version 3.6? 4? something like that) and it was _terribly_ slow, especially on scrolling.

I don't know if ATSUI can be turned off on a Cocoa application, but if it's possible, Pepper should do it (that is, _if_ ATSUI's the source of the problems you mentioned).
