Comment 31 for bug 1777238

@Boris
You should determine which package/application affected and report it as a new bug.
https://help.ubuntu.com/community/ReportingBugs

Check the instructions of these paragraphs:
- Reporting non-crash hardware and desktop application bugs
- Collecting information from a specific package
- Collecting information about a program with a window open
- Collecting information from a currently running program
- Filing a general bug against no particular package
- Complete the bug report filing process

when you created a bug report, launchpad will inform you what else you have to do, like run this or that command..
