Repeatable crash during presentation macOS / LibreOffice 7


I have a reproducible crash when using LibreOffice Vanilla 7.0.1 via macOS App store during presentations. I’m using multiple screens and the slideshow can be induced to become unresponsive with 100% CPU use when you select ‘show slides’. (Currently using macOS Mojave 10.14.6)

Steps to reproduce:

  1. Have a second display (e.g. laptop with hdmi output)
  2. Load a presentation
  3. Start slide show
  4. Select ‘Show Notes’
  5. Then select ‘show slides’

What happens: Spinning beachball and 100% CPU use before ‘Not Responding’ requires you to force quite LibreOffice.

What should happen: Notes are replaced by a scrollable pane of slides, so a user might jump to a slide in their deck.
