Sorry, I don't understand: why would an expose event trigger erasing of a cursor in the minibuffer window? Could you possibly describe in detail the sequence of events that leads to this problem, and perhaps also give a reproducible recipe? And how is this related to the size of the buffer and isearch? Better make all that a bug report. Thanks.
