Hi, I have fixed this in a few places in the wiki:
the combination of natural=water + waterway=riverbank for a single object is pretty dangerous and should be avoided because it will cause subtle and very hard to find rendering problems. The problem I hit was where someone placed a natural=water on some parent relation whereas the riverbanks were multipolygons of waterway=riverbank. The islands that were correctly mapped using multipolygons were flooded by the inherited natural=water. Similarly the advice which was in wiki to tag the multipolygons with natural=water and the ways with an additional waterway=riverbank might cause the same problem.
