Description:
Hi, I have a very simple 5 slide ODP file with 1 picture per slide. I run Impress slideshow using the following command on a Raspberry Pi 3 and have been running happily from the past 2 years using Rasbian Jessie OS running LibreOffice version: 4.3.3.2.
libreoffice --norestore --show --nologo --invisible '/home/pi/OnLine/playppt.odp'

However, on Rasbian Buster OS running LibreOffice version: 6.1.5.2, the slideshow runs for about half hour to an hour and gets stuck at random slides. If I press any key it will transition to another slide but this is a strange behavior that wasn't present in previous version. Please help. Thanks.

Steps to Reproduce:
1. On a Rasbian Buster OS running LibreOffice version: 6.1.5.2
2. Run command: libreoffice --norestore --show --nologo --invisible '/home/pi/OnLine/playppt.odp' (your odp file name)
3. Watch for about 30 minutes - 1 hour
4. Slideshow will be stuck at a point

Actual Results:
Slideshow will be stuck at a point after 30 minutes - 1 hour

Expected Results:
Slideshow should run indefinitely in a loop


Reproducible: Always


User Profile Reset: Yes



Additional Info:
It appears if you run the slideshow directly using the GUI (without the command line), it seems to be running fine.
