System Information
Debian testing, GeForce GTX 960

Blender Version
Broken: 2.76b f337fea

Short description of error
there's a couple issues with freestyle lines on animated objects. the most glaring is that lines often don't seem to know whether or not they are hidden, another issue is that dashes on lines tend to jitter and dance around a lot.

Exact steps for others to reproduce the error
render the animation in the attached blend, and play it back.
alternatively, have a look at what my render result looks like: https://www.youtube.com/watch?v=WKLQIh_EO78

Quite not sure this qualifies as a bug, it sounds much more like TODO’s/known limitations to me, @kjym3?

surely it not knowing whether or not a line is hidden is a bug. note that this problem also occurs in still renders. I can live with slightly odd dashes, but the missing lines make Freestyle useless.

just to make it clear: freestyle rendering is entirely broken in this version of blender. seriously, look at this and tell me that this is even remotely acceptable:

blend file so you guys can test it too:

crate5.blend

can anyone confirm that this bug happens for them too? it's driving me crazy.

Hi Doxin,
Many thanks for the problem report. I can confirm the problem is reproducible on my end. Blender 2.75a gives much better results out of the same crate5.blend file, so the issue is considered a regression. I will take a closer look into the documented bug asap.

Issue seems like a functional limitation of the implementation. But it works as intended. Freestyle Line renderer is an unmaintained area in Blender. @LieuweMosch issue has improved, so closing the report for now. As freestyle merges edges dashes it cannot be used to create the intended style rely-able. Best to use post processing (screen space dashing) or non dashed/thin/less contrasted lines in the original example
