Good news: I can reproduce the bug now using an HP Skylake laptop with built-in 4K panel. Everything freezes if I add an external 4K display.
The freeze does NOT occur if I have DING disabled. If I use both monitors without DING, then only enabling DING makes the freeze happen again. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1976204 Title: Screen freeze if a 4K monitor is added to a 4K laptop while DING is active To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1976204/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
