Please troubleshoot and file useful bug reports for ‘unorganized’, ‘app bar won’t hide’, and excessive resource usage.
Remember that developers cannot fix problems that they cannot reproduce, so useful bug reports are essential to the health of Ubuntu.
If you need help or training to conduct the troubleshooting or to file a useful bug report, the gurus in our support venues https://community.ubuntu.com/t/finding-help/7121 are happy help.
Closing - bug reports do not belong here. Sorry.
