    Classification: Xfce Core
           Product: Xfdesktop
           Version: 4.14.2
          Hardware: PC (x86_64)
                OS: Linux
            Status: NEW
          Severity: normal

For about 5 years now, xfdesktop has been crashing when the monitor powers on
or when the monitor wakes from sleep. Even after seemingly related bugs are
fixed, the problems persists. For example, bug 14609 was closed, but the issue
persists unchanged.
