Broken: Date: 2018-11-30 00:46, Hash: 4c31bed6b46, Branch: blender2.8

Short description of error
Animated object with curve modifier will not be refreshed, when played in viewport. See my attached file for reproduction.

Exact steps for others to reproduce the error
How to reproduce:

  1. Load my scene
  2. Start animation

-> The viewport does not refresh the curve deform modifier. The object will only be deformed when switching to edit mode and back.

Is this a dependency graph problem?

I've posted a video that shows the problem on YouTube too:

No need to assign tasks to developers, we will do that.

All right Brecht. Thank you for the note.

Brecht Van Lommel (brecht) claimed this task.

This appears to be solved in the latest builds.

At the moment my demo scene with some modifiers is at 5 fps in version 2.8.
In v2.79 its faster and runs at about 8 fps.

Will the animation speed be faster some day?

There will be more optimizations.
