Description Richard 2021-07-20 19:35:49 UTC

Description:
Members of our group used Powerpoint to create presentations and when I attempt to display them using Impress on my computer, the response time is extremely slow and generates a program not responding message. I can supply a sample of the pptx file for debugging.

Steps to Reproduce:
1.Load the file.pptx
2. Press F5 to start the presentation
3. Press Spacebar to advance slide

Actual Results:
Extremely slow response time and will generate Program not responding message.

Expected Results:
Would expect a much quicker response time.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
None

I don't see that this was OK with attachment 173764 [details] so I remove regression. 
It actually improved in 5.4, started to show image. 
It was: black and slow with 12 sec, black and fast, flower and 10 sec, flower and 5 sec. And like that in 7.3+ Linux.

JPG has ripple slide transition, but same without it. 
I update the title.

Presentation is a basic feature of Impress, so this is High importance INO.
