Description
Please watch the attached movie.
Accordion is used a lot in SceneBuilder hence a high visibility: yes it works but it's not very sexy.

http://hg.openjdk.java.net/openjfx/8/graphics/rt/rev/f26c68052ab0 This should be resolved to a degree now - from my observations it appears better than it was previously. File a new bug if it persists.

I have done today a comparative check of our b06 (based on FX b113) and b07 (based on FX b117). The vibration problem is very visible, in our b07. There was no vibration, at all, in b06. So, a regression between 113 and 117. The priority, purely from a platform perspective, is debatable and we understand the time/resource issue. But from a SB perspective, this issue is prominent and the accordions are used intensively. We are likely to turn off the animation until this gets fixed -- which is a bit of a shame because we'd love to show off animation in our own UI, obviously.

This is almost certainly related to RT-34060, however on my machine I have always seen this kind of jitter. My opinion is that this should be a P4 targeted at 8u20 that I will try to fix for Lombard, but that would depend on what other issues I have to resolve in the last week and a half of development time that is available to me (at present it seems my bug count is going up rather than down!).

I think I saw it first in b116 and was hoping it would 'go away' in b117. I definitely never experienced it before then otherwise I would of filed an issue. I understand it's late in the day but one of the lovely things about accordion is that it comes with a nice animation. Users will want to use that animation as it makes the control feel slick to use. This unsightly vibration basically negates the work we put into getting this control animated.

I can reproduce when opening and closing a single animated TitledPane. The content 'vibrates' in an unsightly manner. Attaching FXML test case.

I'm not sure I agree with this being a Major bug. Jonathan or Martin can comment on whether the problem is in controls, layout, or animation. Is it a regression (I would be surprised if it is)? In any case, this is coming in quite late in the release, so we may not be able to address it for FX 8.
