15766	Lag when drawing ways with many nodes	anonymous	team	"==== What steps will reproduce the problem?
1. Download some data
2. Draw way with draw tool (Shortcut A) with > 300 nodes
3. 

==== What is the expected result?
No lag. From my experience with the version before this one (13170) 600+ nodes are possible without noticeable lag.

==== What happens instead?
Drawing becomes near impossible with >400 nodes, new nodes are displayed at a rate of about 1 node/second even when clicking much faster.

==== Please provide any additional information below. Attach a screenshot if possible.
