If I start editting a way,add lots of segments to the way. Then when I drag the viewport a little to be able to add more segments, two thing will happen

1. the nodes and lines currently loaded will be removed from the view (normal)
2. the way I was editing will become red and stay in view
3. when I drag the viewport, the way segments will be stuck in their x/y pixel on the screen.
   Three things can now happen
   3.1. no new nodes or lines will be added/downloaded..
   3.2. everything works fine.
   3.3. new nodes are downloaded but the way is still positioned at the x/y pixel

In the case of 3.3 I sometimes get this:

[Node 159906 lat:59.3201332092285 lon:18.0718479156494] to [Node 159905 lat:59.319953918457 lon:18.0706462860107]], [Line 119585 from [Node 159905 lat:59.319953918457 lon:18.0706462860107] to [Node 160904 lat:59.3199462890625 lon:18.0703277587891]]]]
