    When there are multiple Canvases in root Canvas with "CanvasScaler", some child Canvas's RectTransform are broken.

    1. Put a root Canvas (named as Root) with CanvasScaler (UI Scale Mode: Constant Pixel Size, Scale Factor: 2, Reference Pixels Per Unit: 100).

    2. Put two or multiple Canvases (Pixel Perfect: Inherit) which RectTransform is streched as Root Canvas' child.

    3. Play, then one or some Canvas(es)' RectTransform streched mode are broken. As a result, the RectTransform is left-bottom mode.

    Could you file a bug with the example already set up?

    We're seeing something very similar. I can not post specifics in this forum but have a thread in the console specific forum.

    But basically, all our screens have exploded with RC2 and yet worked fine in Beta 23.

    This is not a release candidate.

    To follow up on the thread, we're not able to repro the bug/condition in our upcoming f3. So, unless others provide a specific case/bug report, we're going to assume we've addressed this.

    Hello, @Alex-Lian.

    5.4.0f3 still has this bug of causing children canvases to lock down to the bottom left on play or when reloading the scene.

    @beNice after much trying found the root cause and why it wasn't on every project. I have a fix that i'm running through extensive testing before releasing.
