I've sent the following mail erroneously to Chris only:

I've just tested to set the Background Image to None in order to 
deactive Webkit, restarted Merkaartor, but still, the draging of the map 
was very slow (or better, it took about 3 seconds and then suddenly 
showed the new position). So it's independent of the webkit usage.

I tried to build Merkaartor with NOWEBKIT=1 but that had the same 
problems. Again, all actions performed fast, except the draging of the map.

So it may well be an Nvidia related bug, but it seems to be independent 
of Webkit. By the way the "current" version (0.11) from Debian testing 
worked without any delay on the very same laptop.
