Status changed to 'Confirmed' because the bug affects multiple users.

[Michael Terry (mterry)]

This looks to be callbacks that aren't cleaned up when the panel dies. It looks like upstream's 3.6/3.8 update will fix most of these, as the refresh_ui call seems to be gone/obsolete there.

[Sebastien Bacher (seb128)]

The bug hasn't seen any activity in years and there has been no recent similar reports, the code also changed quite a lot since and it's likely the issue doesn't exist anymore. Closing, feel free to open a new report if you still get problems in recent Ubuntu versions
