    RATIONAL-MA ^^ I have the same issue. I am having weird issues with any Canvas using Screen Space Overlay. Text Mesh Pro also shows a bug with this. This really needs to be patched in 5.6.

    Just switched over to 5.6.
    This is now a big issue and makes ever UI DropDownMenu unusable.

    Another important note is that this especially happens when the Canvas is not Screen Space - Overlay.

    In this particular case for us, it is Screen Space - Camera, which is necessary for the real scenario using this.
