    Currently using v 5.4.1 and I'm having this issue with numerous canvases. Definitely not fixed in this version.

    Is this bug lost inte limbo as it is marked as a duplicate of issue #822354 which marked as fixt (but is NOT)? There is now way of voting on this issue being fixed. My fix is working but still annoying as things look broken in editor (before script fix things on play)

    I just upgraded to 5.4.1f1 from 5.3.5p2 and discovered this bug. Super annoying! My fix (until it's gets fixed for real) is to create a script that corrects the rectTransform settings on Start. That way it kind of fixes what unity destroys.

    It worked for me in 5.4.1f1 to move all the children out of the parent canvas, positioning and saving, and then moving them back in.

    This is a showstopper for us. We have a ton of nested canvases in our UI and cannot use them across mobile devices with differing resolutions. I wanted to give you more information about our use case in case it helps narrow down the issue.

    We have a Canvas Scaler on our UIRoot object set to Scale With Screen Size. Our reference resolution (1334x750 - iPhone 6/6 Plus) looks fine, but on other devices (e.g., iPhone 5 at 1136x640) the nested canvases are both anchored to the bottom left of the root canvas AND scaled down. This happens in both play mode and on-device. So even if we have our game window set to 1136x640 to emulate an iPhone 5, the UIRoot canvas is still set to 1334x750, but all nested canvases are set to 1136x640 and as such, don't take up the full dimensions of the screen.

    Weirdly, if our nested canvases are set to World Space, the dimensions are correct (i.e., they take up the full width and height of the UIRoot canvas). But then we lose out on being able to override sorting order, which we need for UIs overlaid on other UI elements (we ideally want the nested canvases to use Screen Space - Overlay).
