[Launchpad Bug Tracker <1576228@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

While using the nvidia proprietary drivers in 14.04 - 16.04, my Dell XPS
L501X resumes from suspend, but displays wide black borders around all
windows with close/minimize/maximize buttons blacked out as per attached
screenshot. It occurs inconsistently, as it doesn't happen every time
the computer resumes.

Also there seems to be certain amount of performance degradation as if
the graphics driver was running at half-strength. The "nVidia X Server
Settings" app suggests its in maximum performance mode.

Adhoc WORKAROUND: switch display layout (I have an external monitor/TV attached to HDMI port) changing anything such as arrangement or resolution of the displays, etc. corrects the black border issue.
(update: Adhoc WORKAROUND no longer works with nvidia 375.39)

Adhoc WORKAROUND 2: type "unity" in terminal
i.e.
user@machine:-$ unity
(that should restart unity/compiz)
(and kills/closes some (read: web-browser) windows)
 
See comment :https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-361/+bug/1576228/comments/4

WORKAROUND: Use nouveau.
