If you are experiencing a bug in Xfce
, your way of helping things getting fixed is to report a bug about it in Xfce GitLab. Please note that to do this you will need to have / create an account.
When writing your bug report, try to be as descriptive as possible, but avoid verbosity; Mozilla has a nice guide on how to write a bug report.
For more information, see Bug Reporting and Fixing.
