As Dave pointed out, the problem is not consistent with black borders
but also with graphical glitch around windows, which I still think, has
something to do with, how shadows are rendered.
Adding an alternate attachment/image for graphic glitch.
** Attachment added: "Graphically glitched
** Description changed:
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
Yes, I think that is the bug that affects several, if not many of us, in
our workplace. We use Dell XPS-15-9550 laptops. I have Ubuntu 16.04
with proprietary Nvidia driver 361. I use this driver rather than
nouveau, because its better support for connecting to HDMI TVs.
The borders are broad
** Description changed:
- There seems to be a bug somewhere in [ kernel OR xorg OR nvidia proprietary
driver ] in the display stack.
- After the laptop ( dell XPS L501X ) resumes from suspend there are wide black
borders around all windows with close/minimize/maximize buttons blacked out.

(Switching back to proprietary nVidia driver) results in (graphic
corruption after resume from suspend)
However it seems there might be some issue related to how shadows are
rendered. Using nouveau, there are no shadows, and windows have borders
instead of being borderless with shadows.
I'm not
It seems the problem might have something to do with how shadows are
rendered, AFAIK using nouveau has disabled shadows (possibly due to
lower performance of graphics card on nouveau) however the shadows are
enabled using the proprietary Nvidia driver 361.42...
I'm just guessing the shadows are
Hey penalvch,
After almost a day of using nouveau, there doesn't seem to be any black
border after resume from suspend, however this might be because of low
suspend-resume cycle count.
I'll post update if the issue occurs on nouveau.

Hey Christopher,
Always a pleasure to contribute.
I have switched over to nouveau, but since the issue occurs INconsistently
I cannot immediately reproduce the bug condition. I'll most likely have to
wait and watch for suspend-resume cycles to check if the bug gets
reproduced .
Meanwhile there
I sorted out the suspend issue (turns out I had inserted a faulty memory
card in the laptop and as it was unable to get data 'sync' to it hence
systemd was assuming that suspend transaction would be destructive :D )
I'll try to use nouveau for a few days, see if black border issue
persists or
Another thing that might help in triage is as per the workaround
specified,
Changing screen position (in a 2 monitor setup: laptop + HD TV(via HDMI) )
corrects the problem,
Important thing to note is that you can use [ nvidia-x-server-settings ] or [
gnome program: Displays] to do it, in either
1. The black border issue is inconsistent so cannot verify whether using
nouveau fixed it or not.
2. My HDD seems to be giving-up as the read-error-rate is at: 6033
->Which seems to result in btrfs errors/panic in syslog
-> -> Also which seems to prevent `suspend` at the moment

John Smith, thank you for reporting this and helping make Ubuntu better.
To clarify, if you remove the nvidia drivers is this still reproducible?
