I have same issue on my laptop (Dell Precision 5530) when using nVidia graphics, with latest official proprietary driver. But it does not appear when using integrated Intel graphics, everything works fine in that case. ** Attachment added: "IMG_20190910_130806.jpg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1827314/+attachment/5288233/+files/IMG_20190910_130806.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1827314 Title: Ubuntu 19.04 Background and lockscreen image turns into white noise after sleep and wakeup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-desktop/+bug/1827314/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
