Lines being drawn with a LineSymbolizer width that's fairly large (in my case, 16), curves have a very visible break in them when angles change.

As per springmeyer's suggestion, I set linejoin and linecap to multiple different options, but none had any noticeable effect.

Attached is an image highlighting the breaks. Two lines are being drawn, a black one underneath with a width of 18 and a yellow one with a width of 16. Both are exhibiting the "undesired" behavior. Occurs with cairo as the renderer and without.
