Comment 15 for bug 1747566

I'm having the same issue still using a new Ubuntu 18.04 LTS with all of the latest package/kernel updates. This is also causing VERY large syslog files (5-10G each). The errors I'm receiving are related to tweener.js so I'm updating this bug report instead of opening a new one:
