Desktop missing after resuming from lockscreen

[Krister Swenson]

I have a periodic problem where, when returning to the computer and swiping up on the lockscreen I have an unusable desktop. The sidebar is present and the elements act as expected (click shows the windows open for the app), except for the grid icon at the bottom which is unresponsive. The menus in the top right corner are still present, yet many of the options are missing, including the option to logout, and the option to reboot. Only the suspend button appears. The desktop seems to be replaced with the same wallpaper as the login screen.

The only times I've had this occur were when I had at least one full screen app open. The first was a paused youtube video and the second was a REMMINA session.
