When you press the "GPS data" button in Potlatch 2 you only get a few "pieces" (literally just a few parts of the whole trace) of the traces that you know are in that area, but when you press the G key in Potlatch 1 you get all the traces right.

Replying to [ticket:3572 julio.costa@]:

P2 seems to

  1. Only draw those segments of a track that both start and end within the window.
  2. Draw connecting lines between the end points of all tracks drawn.
    This leads to many artifacts near the edges, especially on a road with many traces made at high speed, like a freeway.
    Hopefully simple solutions:
  3. Use a larger window when selecting "visible" segments.
  4. Move, instead of draw, when switching between different tracks.
