[Bug 1576228] Re: Black borders around all windows
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 borders" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-361/+bug/1576228/+attachment/4825203/+files/Graphics%20Glitch%20-%202017-02-23%2017-45-26.png ** Summary changed: - Black borders around all windows + Black borders or graphic glitch around all windows ** Summary changed: - Black borders or graphic glitch around all windows + Black borders or graphical glitch around all windows -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576228 Title: Black borders or graphical glitch around all windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-361/+bug/1576228/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1576228] Re: Black borders around all windows
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 and not always completely black, sometimes they are dominated by coloured lines and sometimes they include odd character glyphs, particularly at the corners. (I say this just to help other recognise their problem as this). Thanks for the workaround, up until now I have had to reboot. But yes, if I change the screen layout using System Settings -> Screen Display when I have an extra display connected, then all is recovered. I guess there ought to be a more direct way of refreshing screen configuration, but this workaround is easy enough. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576228 Title: Black borders around all windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-361/+bug/1576228/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1576228] Re: Black borders around all windows
(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 familiar with: how the shadows are rendered, but there might be some bug with shadow rendering path. ** Attachment added: "Graphic corruption around windows" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1576228/+attachment/4685624/+files/Screenshot%20from%202016-06-17%2018-33-08.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576228 Title: Black borders around all windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1576228/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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...

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.

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 case as soon as I click 'apply' the black border issue is corrected. i.e. [ 'change position of either screen' -> 'click apply' -> screens blackout -> screens re-appear -> revert to previous configuration (or not) -> black borders gone ] -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576228 Title: Black borders around all windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1576228/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
