I am using Libreoffice 7.1.4.2 under Ubuntu-MATE 21.04. According to the LO's about dialog: User Interface: UI render: default; VCL: gtk3

I only use the text processing „Writer“, nothing else.

enter image description here

Problem 1: my styles panel (on the right) on the right flickers all the time

...blinks, maybe 50-100ms to white and back... (but certainly not in a blink tag fashion, more of a “nervous redraw”)

  • basically irregulary about once per second (1 Hz)
  • more often with every keypresses happening
  • not at all, if focus is on another application's windows
  • only in the styles panel

So apparently triggered by some refresh mechanism.

Problem 2

I assume it's related, thus in one post. LibreOffice freezes my entire machine:

  • mouse still movable, all screens showing (3 in total, including 2× 4K)
  • that's all – no clicks, no hovers, no interaction
  • no keyboard commands (i.e. for Run or Terminal or alt-Tab) working
  • not even ctrl-alt F3, F6, F7 (for non-graphical login)
  • only hard reset + reboot helps

Any ideas?

What log file to look into? How to put LibreOffice into a different rendering mode?

For the flickering, I had the exact same symptoms and found a solution in this thread.

The problem is probably an old, deprecated .xinputrc file in your home directory. Just delete it, reboot and the problem is solved. At least it worked for me.

  • Due to this and several other problems I decided to reinstall my machine from scratch, so I can't reproduce, neither good nor bad. — but truly thank you for your help! – Frank N Oct 21 '22 at 07:58
