My Garmin Colorado 400t gives me just one huge Current.gpx file that I need to split up anyway (and label the individual tracks with something more useful than "Current Track: 12 JAN 2012 12:49"). > no.

I thought that, too, but the problem seems to be the same regardless whether the trackpoints are visible or not. Surely it could ignore tracks, or TrackWaypoint layers, that are turned off? > I have been thinking about that, and in particular using > postgresql/postgis, so that viking can query for all tracks that > are in the viewport.

I'm encouraged by your description of the skip_same patch. I really need to get around to upgrading, starting with the OS. > I think it's a combination of viking asking for a lot of drawing > and the X server not coping all that well. I'm persuaded you're probably right--certainly a good place to start. Thanks for your comments and advice.
