Build from today (2019-01-28). Freestyle seems to show some other issue going on. The mirrored copy of beveled curves (full fill mode) do not receive freestyle lines:

Updating blender2.8 -> master in my local repo, and rebuilding, showed the problem is resolved. :)

In 2.80 (built within the week), in Linux (Debian stable w/official Nvidia drivers), appending objects from a 2.79 project, then Freestyles enabled, also results in a black render. The render layer also appears black in the compositor -- and only when Freestyles is enabled -- the objects show fine when freestyles is disabled.

Are these assignable in the Prefs -> Input? I can't find them.

Not reproduced in Win10, 2.78a, with a GeForce GTX 560 Ti.

Indeed, but there seems to be some issue with the user count not dropping to 0 when a slot is removed.

Thanks Tamito,

It appears having 14 children is an issue. When changing it down to 1 it doesn't bog down. 3.4ghz cpu too.

I did not notice the instructions not to post feature requests here. My apologies. Please feel free to close this or, better yet, do me the favor of placing it somewhere appropriate. Somewhere where the Sun shines.

Click and drag of nodes also breaks with Enhanced 3d Cursor enabled

More details:
Blender must be started with the addon already enabled for tooltips to fail.
Then, toggling it off will re-enable tooltips.

It doesn't crash with the latest builds. Interesting. Thank you. Shall we mark as fixed?

Was trying for hours, even prior to posting. Will update if I successfully get it to fail.

Alt-H seems to show the edges again.
Which brought me to the recollection that I did hide parts of my mesh somewhere in the mix.
I crashed blender in testing this this .blend (a mix of selecting, toggling selection, hiding, toggling edge display, etc.).
