There's a vertical black bar on left side of screen. Can't get rid of it with Settings Displays or xrandr. Acer Aspire 1 D255E with 1.5.5" external monitor set to 1366x768 (will run up to 1920x1080). See screen capture attached. Launcher normally hidden. Mouse over, launcher shows and fills the black bar. Then launcher hides leaving a vertical sliver of the desktop and a vertical black bar. Appears that the code to restore the desktop after launcher hides is not working.
