Hi c3d, we had a similar report recently about high CPU usage that turned out to be a troublesome extension rather than LibreOffice itself:
https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1825513 Do you have any additional extensions installed? If you do, please disable them and let us know if the problem goes away. Thank you! ** Changed in: libreoffice (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1824264 Title: CPU gets to 100% when Libreoffice is idle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1824264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
