An intermittent problem, sometimes after I resume from suspend there is no desktop only a single purple colour covering where the desktop should be. Also if I go to the menu (top right) options are missing for settings and restart so I can only click the pause icon to suspend again.
I cannot see any applications in this state. They are running as I can see their icons in the taskbar strip but no apps can be seen due to the blank purple desktop.
This happens maybe 10% of the time I resume from suspend.
