Ive always solved this with Ctrl-Alt-F1 and Ctrl-Alt-F7. I get same picture as #81.
With update from an older/driver to kernel to 4.4.0-47 and Nvidia driver 378.13 Ctrl-Alt-F1 and Ctrl-Alt-F7 does not remove the borders anymore.
unity --replace fixed it (but makes Google Chrome render all windows black until I restart Chrome)
