I recently upgraded Ubuntu 14.04 to 16.04. On my computer I used to replace Nautilus with Nemo. Since Ubuntu was upgraded, it looks like Nemo is no more able to handle the desktop display. Instead of displaying the desktop background and the icons, a black blank screen is displayed (the lateral navigation bar is still present and applications open the right way).
It seems Nemo is no more able to handle the desktop the right way, at least on this computer. I manage to have some ghosts displays when moving a application window over the desktop. Maybe a display driver issue (AMD ?)
