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
