Roughly what I did: I attempted to minimize the main FL Studio window while it was maximized. The small blue label appeared which shows the program's title "FL Studio 12" as the text. I pressed the minimize keyboard shortcut which then properly minimized the application.
Then I restored and unmaximized the window, and attempted to minimize the FL Studio window again (which made the blue label show up again). Then I tried resizing the main window which as previously described shows trails/after images. Pressed minimize keyboard shortcut which then properly minimized the application and then restored it and closed it.
