Magnus, Dane, Thank you for pointing out this issue and a solution. I have seen it before and just blamed the GPS receiver without thinking about it properly. I will go and try the soloution on one of my maps....

Yep, rendering artifact, that I can replicate. Your hunch was right. Not looked closely yet as to the cause, but likely the high density of nodes triggers those sharp spikes in some part of AGG. The fix, however, is easy, and likely something want you want anyway for smoother a looking line given the high density of node. Add these two extra options to the LineSymbolizer: stroke-linejoin="round" stroke-linecap="round" That should fix things up nicely. Though your pre-processing solution is great too of course because things will draw faster that way.
