On the chance that the visual corruption is unrelated to the log messages, it might be a recurrence of an issue we saw during development on hybrid systems. Basically the integrated GPU would have corruption if Nvidia was updating at the same time (full screen animations). Red Hat told me they had found a workaround and that's what we're shipping already. But if you still have the corruption then it should be possible to eliminate by adding this to /etc/environment:
MUTTER_DEBUG_FORCE_RENDER_SOURCE=0 and rebooting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2147324 Title: Visual artifact when changing screen content To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2147324/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
