If I use a right-click on my mouse anywhere in LO, it crashes and restarts.
What Linux distrib do you use? How did you install Linux? from repos of your distrib or in another way? Could you give a try to https://wiki.documentfoundation.org/QA/FirstSteps? If you still reproduce the crash, would it be possible you attach a backtrace by following this link? https://wiki.documentfoundation.org/QA/BugReport/Debug_Information#GNU.2FLinux:_How_to_get_a_backtrace
I use OpenSuse tumbleweed. Because its a rolling-release-distro, I got some updates yesterday and now the problem is gone... No clue, what the reason was...
Thank you for your feedback, let's put this one to WFM then.
