gpx layer: downloaded data not shown right away.

[skyper]

Hey,

I have three layers from top to bottom: one osm-data, a gpx-layer with downloaded gpx-tracks from osm-server and one imagery (Bing).

The osm-data is activ but hidden.

If I download more gpx-data from osm-server in the same layer the new data it is only shown after some action (I use zoom).

I am using r4018 but I thinks it happens for quite some time.
