6197	slowdown if gpx is above data layer	richlv	team	"""latest"" 4002.
if a gpx is above data layer, josm becomes much slower (panning, adding nodes/ways etc).
if the gpx is moved below data layer, performance improves a lot.

possibly more visible with larger gpx & data layers, definitely observable with 1mb gpx & large-ish data layer."	defect	closed	normal		Core	latest	fixed
