Maybe Acrobat treat Rect as float and QuadPoints as double.

    ~5 years later this bug still exists in Acrobat. The definition of the QuadPoints is that they need to be defined inside the are of the Rect. It looks like there's a bug in the comparison of float values in Acrobat because this sometimes works and sometimes not.

    The files provided by Hiroki shows the faulty behavior perfectly: In the test-1_ok.pdf the QuadPoints are taken into account and only the underlined words are clickable.

    OK.png show the Rect and the QuadPoints.
    NG.png shows only the Rect and the QuadPoints are ignored.

    Hi Hiroki,

    Thanks for Reaching out to us.
    The behaviour difference that you are getting with the Good and Not good files is just because of the Link that is created for both these files is differently.
    Thus, the cursor icon on hovering on the linked text is appearing differently for both the cases.
    Its just the ways these links are created by the respective pdf producer for both these files.

    To check the actual link location on the View, Go to Edit app -> Click on Links dropdown and select Add/Edit Web or Document Links.

    Thanks,
    Ammar

    QuadPoints surround the blue texts.
    I expect cursor is chenged when cursor on the blue text.
    But only text-1_ok.pdf work correct at Acrobat DC.
