"Render Animation" doesn't refresh bone constraint to rendering frame

Description

OS
Windows 8

Blender Version
Tested on 2.71, 2,72, 2.72a

Problem
I have hands of character constrained as children of a gun, which "lag" behind when scrubbing back and forth in the viewport.
While this in itself is annoying, and probably a bug, the problem is worsened by the fact that this lagging carries over to "Render Animation", so the hands/arms would be in the wrong place.

This doesn't happen when rendering out single frames. Fine for single images, but for animation, this is a big headache.

This is a known issue in our current depsgraph, there is a workaround for it though - enable Extra Object Update and/or Extra Data Update for armature and ant mesh, in Object buttons, Relations Extra panel.

Anyway, not a bug, rather a known TODO for our future new depsgraph. ;)

Ah, my apologies. The workaround worked like a charm! Makes me wonder why something like this isn't enabled by default, haha.

Anyways, thank you! I guess that new depsgraph will solve so many things.

Having the same issue, but don't see those options in 2.8. Was that issue corrected or am I looking in the wrong place?

Hey, I'm having the same problem in 2.8, All my animations are with one constraint following another bone with 1 frame delay in the exports in Unreal and Unity. This Extra Object Update and Extra Data Update were working pefectly in 2.79, but I can't find it in 2.8.

changing with the mouse between the frames (14-15) you can clearly see the problem

@Rafael Brum (RafaelBrum) Please do not resurect old tasks, especially when they do not cover the same version of Blender at all. This requires a new report, with all needed info.

Sorry, I didn't saw it was old. I'll create a new report so.
