Thanks. It seems Nvidia isn't relevant here. The error is occurring on /dev/dri/card1 which is your integrated Intel GPU.
Actually I saw issues on Intel GPUs last night. Not corruption but it seems like it might be related to your error messages. Now that you have Mutter 50.0-0ubuntu3 installed, please reboot so we get a clean system log. I am hopeful you will find the problem is gone. If not then please run this again: journalctl -b0 > newjournal.txt ** Tags removed: nvidia ** Tags added: i915 ** Tags added: nvidia ** Tags removed: nvidia -- 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
