Public bug reported: On a fully patched 16.04 Ubuntu 11/9/2016, running a default Libreoffice installation (1:5.1.4-0ubuntu1) with just a browser running, start the system monitor. Open the Libreoffice Word icon in the Dash, and type in two lines in different fonts: Liberation serif originally. Bitstream Charter originally.
Select both lines (which may be as short as one letter), and change the font in the font input to comic sans, while watching the system monitor (default settings, cpu history). Note all cpu traces are near the 0-20% range. One cpu trace will quickly go to 100% and stay there. On my system, I get 8 cpu traces, while the cpu may change, one will stay at 100% until exiting the document. No further actions are necessary to keep the cpu at 100%. At the document exit, a dialog will appear, asking to "Save change to document "Untitled 1" before closing?" with buttons below -- frequently (but not always) the entire dialog window will be blank, but the invisible "Dont Save" button will still work if clicked. askubuntu question http://askubuntu.com/questions/847567/libreoffice- uses-100-cpu-after-changing-the-font-of-a-whole-document has indicated that Libreoffice Calc displays the same problem, so the problem is probably in the common or core Libreoffice package. First two cells, letter A in Liberation serif and next cell B in Bitstream Charter, select both lines, and change font to comic serif -- a cpu quickly goes to 100%. $ lsb_release -rd Description: Ubuntu 16.04.1 LTS Release: 16.04 $ apt-cache policy libreoffice-core libreoffice-core: Installed: 1:5.1.4-0ubuntu1 Candidate: 1:5.1.4-0ubuntu1 Version table: *** 1:5.1.4-0ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu xenial-security/main amd64 Packages 100 /var/lib/dpkg/status 1:5.1.2-0ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu xenial/main amd64 Packages ** Affects: libreoffice (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1640632 Title: Libreoffice Word uses 100% cpu after font change To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1640632/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
