@seb128 I've removed the v4l2 loopback module. That stopped the kernel driver issue you mentioned. The problem with the artifacts persists. Now it's on my laptop screen without the external display being preset.
Note: This is only when I run on the internal intel GPU. It doesn't happen when X uses my external nvidia one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874543 Title: Artifacts when connected to an external 4K display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1874543/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
