dreamcat4, Ubuntu 19.10 is not supported. It reached end of life on July 17, 2020.
This is a bug/design feature of Xorg graphics drivers like Nvidia and AMD's. You can work around it either by explicitly configuring the driver to sync to the fastest monitor, or by enabling "TearFree" if available. For a more long term permanent solution, using GNOME Wayland sessions should never hit such a problem. But that also requires your graphics driver support Wayland sessions :( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1820832 Title: [xorg] multiple monitors: limits the framerate of faster 120/144hz monitors to 60hz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1820832/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
