since unity 5.5, scrollbars can't be disabled anymore, when they are linked to a scroll rect

Is this kind of a new “feature”?

We have our own functionality for scroll areas, that hides (disables) the scrollbars, when the vertical scroll content fits in the scroll area. then the content takes the whole width.
otherwise the content will be inset on the right by 20 pix and the scrollbar will be displayed.

but that does not work anymore. now there are scrollbars all around over the content in the scroll rects, because they can’t be disabled anymore.

there are no infos about these changes at all.
i know there is kind of an comlicated way to do this via viewports. but why we are forced to switch from our system to something else, when it has worked just fine?

Yes, this is something new, I need to disable srcollbar when game start, and then to show it later. It was working in 5.4.
Now in 5.5 you cant disable it, even in editor.
Unity team, please explain this new behaviour…

Did you guys file a bug report? That’ll force Unity to at least look at the problem.
