  7-10 seconds and the system takes the same amount of time to respond to
- perform individidual scrolling gestures to move through the list.

+ whole system becomes unresponsive.
  
  I have tried deb, snap and even the packages offered on the site of the
- LibreOffice project. They all manifest the same behaviour. I have had to
- downgrade to 7.2, which appears to be unaffected.

  I have contacted the LibreOffice team and they tell me that this should
  be solved by fontconfig 2.14. Unfortunately, Ubuntu 22.04 is shipping
  2.13...
