Comment 9 for bug 2063970

Yes, it happens randomly, but I noticed how you can reproduce it, have a few apps minimizrx, open an app in fullscreen, click on top of screen beside clock and click once in an empty area, the fullscreen window becomes a halfscreen with the orange color showing, klick again and you will see all of your minimized apps as icons in the destop. When you move a window aroun, the orange overlay disappears, and if you maximize the app that caused it it will not happen again untill you close it and restart it.
