            Bug ID: 135419
           Summary: Sometimes animations and transitions are ignored by
                    Impress
           Product: LibreOffice
           Version: 6.4.5.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: raj at rafa.eu.org

Description:
In some old presentations that I have on my disk, animations and transitions
are handled incorrectly in the current LO. This happens only for some
presentations, and only for some slides in them; for others everything is all
right. The file I used to demonstrate the issue is probably the most severe
case I found.
These presentations all opened correctly in OpenOffice 3.2.

Steps to Reproduce:
1. Open the sample file http://rafa.eu.org/share/lo_issue/murach.odp
2. Start the slideshow.


Actual Results:
1. On the first slide, after clicking the mouse, the text "Geography" appears
together with the map picture (this is correct).
2. After a short delay, horizontal and vertical dimensional arrows appear, but
they don't seem to be animated (this is only partially correct, because they
should be animated).
3. Immediately after this, Impress advances to the next slide (this is
completely incorrect, there is a lot more to display on this slide).
The behaviour is shown on the video:
http://rafa.eu.org/share/lo_issue/transition.new.ogv

Expected Results:
1. On the first slide, after clicking the mouse, the text "Geography" should
appear together with the map picture.
2. After a short delay (1 second), horizontal and vertical arrows should
appear. Horizontal arrow should be animated from right, vertical one from top.
3. After a mouse click, a block of text "area: 889 km2" should be animated from
the left, followed by several more blocks of text every 2 seconds.
4. After last block of text is displayed, Impress should wait for mouse click
before advancing to the next slide.
The correct behaviour (recorded using OpenOffice 3.2) is shown on the video:
http://rafa.eu.org/share/lo_issue/transition.old.ogv


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
The behaviour is unpredictable when I try to edit the animations/transitions.
For example, when I change the text block "area: 889 km2" to be displayed after
delay instead of after a mouse click, the behaviour is completely different:
1. At the beginning of the slide show, there is no wait for mouse click, the
text "Geography" with the map picture appears right away.
2. After a short delay, horizontal and vertical dimensional arrows appear
(without animation). This is the same as in the initial result.
3. Immediately after this, all  blocks of text appear at once (without any
delays or animations) and Impress waits for mouse click before advancing to the
next slide.
This behaviour is shown in the video:
