17263	"GpxLayer sometimes shows ""ghost lines"""	GerdP	team	"==== What steps will reproduce the problem?
See #17257. 
Sometimes ""ghostly"" gpx lines appear on the screen and disappear again either the plugin loads more data
or when you move the cursor or force a repaint by deactivating and activating again the GpxLayer.
==== What is the expected result?
No ghost lines
==== Please provide any additional information below. Attach a screenshot if possible.
The problem is in class `GpxDrawHelper`. This class modifies the fields of `WayPoint` instances, e.g.
drawline and dir. Therefore the result of the first call of of `GpxDrawHelper.listVisibleSegments(Bounds box)` differs from that of following calls.
