Since the corresponding information is buried in a couple of long threads, here’s a quick summary of how to make LibreOffice reasonably fast in Qubes. Use it, if you experience high CPU usage when using LibreOffice and/or LibreOffice to be extremely slow, lag when scrolling, etc.

launch LibreOffice like that:
SAL_USE_VCLPLUGIN=gen libreoffice

Furthermore, in LibreOffice, Tools → Options → View

  • Disable hardware acceleration
  • Disable anti-aliasing
  • Enable “Use Skia for all rendering”
  • Enable "Force Skia software rendering”

kf5 works better than gen. The rest doesn’t matter.

At least on my 4.2.4 system.

Never had issues in LibreOffice even on modest old hardware. Will try this if I do though.
