Description Daniel Collins 2022-05-21 02:51:16 UTC 
Description:
Working as a college math professor, most undergraduate textbooks come with premade Powerpoint lecture slides from the publisher. I would like to present these with Libre Office Impress. However, in every case the animated OLE math objects fail to animate properly. This is consistently the case across a large number of textbooks, authors, producers, etc., that I've tried to use (working mostly with Pearson textbooks).

Steps to Reproduce:
1. Open the PPTX file
2. Start the slide show, proceed to slide with OLE animations, click through (e.g., in attached file, slides 5, 7, 8, etc.)

Actual Results:
OLE objects fail to animate (in view at all times)

Expected Results:
OLE objects should animate (start invisible, then transition to visible on click)


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
- Note that text objects animate fine; it is only OLE objects (math images) that do not.
- If the PPTX file is converted to ODP, the problem persists (OLE objects do not animate)
- Although though the OLE objects don't animate, the slide still "eats up" the expected clicks; we must click as many times as OLE objects to get to the next slide
- Even if we delete all the animations on a slide, these "hidden" clicks persist; we must still click as many times as objects to get to the next slide
- Trying to backtrack to the previous slide often fails on slides with OLE animations that we tried to remove.
- I can provide an arbitrary number of publisher-made PPTX slide decks with this problem, if desired (e.g., hundreds)

Publisher-made PPTX with OLE animations.

Animated OLE objects start on slide 5.
Comment 2 Daniel Collins 2022-05-21 03:08:31 UTC 
Note that on conversion from PPTX to ODP, OLE object animation entries are lost from the Animations sidebar. E.g., in the attached PPTX example, on slide 5, there are 5 animations listed -- 2 text and 3 OLE embedded objects. After conversion to ODP format, only 2 animations are listed -- just the 2 text objects. Nonetheless, the slide still "eats up" 3 extra clicks for the missing OLE animations.

Comment 5 Buovjaga 2023-01-12 12:48:19 UTC 
I reproduced the problem in older versions, but it is fine now in 7.4.3.

I found a problem in an unreleased version and reported it as bug 152990
Comment 6 Daniel Collins 2023-01-12 17:32:41 UTC 
Agreed, confirmed this works for me now with the 7.4.4.2 download. Major fix for me, thanks to whoever made that happen.
