Mattias Lundmark, to advise, the scope of this report is only LibreOffice crashing (not other programs, or collateral damage from this).
Regarding the GPU hang, and x ultimately crashing causing the session to be booted back to the login screen, it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal: ubuntu-bug xorg Also, please feel free to subscribe me to it. ** Changed in: libreoffice (Ubuntu) Importance: Low => Medium ** Changed in: libreoffice (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1576163 Title: Libreoffice crashes when opening a dialog Status in libreoffice package in Ubuntu: New Bug description: When any type of dialog window opens, libreoffice crashes causing lightdm (unity?) to crash aswell. Since not only libreoffice crashes, but also lightdm/unity, all programs will stop causing work in progress to be lost.

Should be of high importance since all work in progress is lost dues to complete lightdm crash.
