            Bug ID: 132777
           Summary: "Blink" animation timings are not applied correctly.
           Product: LibreOffice
           Version: 6.3.5.2 release
          Hardware: x86-64 (AMD64)
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: mgiubileo at computeraltafed.it

Description:
The timings of the "Blink" animation applied to an element are so wrong that
the effect is unusable.

Steps to Reproduce:
Let's suppose we want to apply a blinking effect to some element in a page (not
just to a text).

1. Create a new presentation and create some element like a Rectangle or an
Ellipse.

2. Select the element and add the "Emphasis: Blink" effect to it, and set the
Duration of the effect to some value like 10 seconds.

3. Start the presentation (F5) and click to start the animation.





Actual Results:
You'll see that the animation duration is not what you set, but something like
the half of it. For example, if you set a duration of 10 seconds, the animation
will only last for 5 or 6 seconds.

Expected Results:
If I set a duration of 10 seconds (and no repetitions) I expect the animation
to last 10 seconds.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
Another problem (I think is related to the above problem) is that if you want
to repeat the blinking animation (well, usually just a single blink is not much
useful!) the blinking itself will be very strange, much much faster of what you
would expect and not much usable, because the time the element is visible is
too little compared to the time it's hidden. For example, if you set a Duration
of 1 sec and a Repeat value of 10, you would expect 10 blinkings of 1 second
each one (so, the animation should last 10 seconds in total). Instead, what you
get are 10 strange blinkings (as I said before, during a single blinking, the
time in which the element is visible is too little) in about 5-6 seconds.

Bug present on versions: 6.3.6.2 (x64) and 6.4.3.2 (x64). I don't know if it
affects earlier versions too.
