"Lost in the Thread" is nice - might be the title for the next "Lost in
Translation" movie :-)
The problem I was referring to is that (previous to the last patch) it
took merkaartor forever to work on the map in high zoom levels - with
you mentioning it was due to QT not performing a proper clipping to the
area, thus requiring lots of memory if a relation member is among the
things in the map section currently being viewed. The "relations" part
of the problem seems solved, but the very same effect is still present
for border-type ways. Those are usually not part of a relation, but are
also quite large (might also apply to any other "big" map feature). My
guess is that there's more things in the map currently not being
properly clipped away.
Hope this helps,
