17596	[Patch] No lines displayed for GPX tracks without tags	Bjoeni	team	"Regression of #16963: Lines for local track segments without tags (timestamps/name etc) aren't drawn, only the individual trackpoints are visible.

>The [https://www.topografix.com/GPX/1/1/#type_trksegType Gpx standard] clearly states 
> >A Track Segment holds a list of Track Points **which are logically connected in order**. To represent a single GPS track where GPS reception was lost, or the GPS receiver was turned off, start a new Track Segment for each continuous span of track data.
>so the data returned by the server is completely invalid, but pretty much all the other files on this planet still follow the standard. And there are plenty of reasons for tracks without timestamps, including privacy and artificially created ones (to display a route).

>I see two options:
> - The OSM website guys actually care about the GPX standard and create an extension that allows them to add unordered points to a GPX file (I don't really see this happening, though I haven't contacted them). They could also create a new segment for each point but that would probably result in too big files.
> - We only define segments as unordered when the file is coming from an OSM server (so essentially a hack... because our own system breaks the standard).

>It seems ""Convert to GPX layer"" doesn't fully work. When I convert an untagged way only the GPX points are displayed This changes when I add a name tag to the way before converting. Seems to be a problem in the renderer as the TrkSeg information is not lost when I safe the converted layer to file."	defect	closed	normal	19.04	Core	latest	fixed	regression gpx conversion renderer
