Is your graphic card driver up-to-date too?
You can try this:
https://wiki.documentfoundation.org/QA/FirstSteps

but if you still reproduce this, the only next step I see to investigate is to build sources with symbols+debug enabled https://wiki.documentfoundation.org/Development/BuildingOnLinux
Now you must know that the build process make take some hours depending on your config.
