Using Content Size Fitter or Vertical Layout Group causes error

UI

-

When using the Content Size Fitter OR the Vertical Layout Group components on the Content of a Scroll View, and playing the scene an error pops up:

Trying to add (Layout Rebuilder for) Content (UnityEngine.RectTransform) for layout rebuild while we are already inside a layout rebuild loop. This is not supported.
UnityEngine.Canvas:SendWillRenderCanvases()

2. How we can reproduce it using the example you attached:
See the attached video.

1. Create a Scroll View add Text GO to its Content
2. Add the Content Size Fitter component on the Content
3. Press play
4. Notice the error. Exit play mode
5. change the attributes of the content fitter: Fit - minimum size
6. play again
7. Notice the content size is now fixed
8. set the attributes of the content fitter: Fit - Unconstrained
9. play again,
10. the content size is still fixed

    Karl said in forum that he put backport request for this. So it's probably going to be fixed in 5.3.1p2 or p3

    Not fixed, terribly annoying, and the worst part is Unity tells you to do it in their videos: https://unity3d.com/learn/tutorials/modules/beginner/live-training-archive/creating-scroll-lists-at-run-time

    Just more proof that unity needs to spend more time actually using their tool, to actually make games, like almost every other engine developer

    This is ridiculous. Firstly, it's not a duplicate of #739376. Secondly it's not fixed. Unity's QA in it's full glory...

    I would like to add all my votes to this one.
    It totally breaks my UI and I can't find a workaround.

    Also having this problem, and for the same reasons, in 5.3. It worked okay in 5.2.x.

    This has started occurring in one of our layouts as of 5.3 and I've not yet found a workaround.
