When this bug was first reported in 17.10 it was a Wayland-only bug and the fix for that is awaiting review: https://gitlab.gnome.org/GNOME/mutter/merge_requests/171
However since 18.04, a patch was introduced to Ubuntu/Debian that seems to be affecting Xorg sessions now too. So I think that also needs removing to fix this bug: clutter-Smooth-out-master-clock-to-smooth- visuals.patch ** Summary changed: - 144Hz/120Hz monitor but Wayland sessions seem to cap rendering at 60FPS + 144Hz/120Hz monitor but mutter seems to cap rendering at 60FPS -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1763892 Title: 144Hz/120Hz monitor but mutter seems to cap rendering at 60FPS To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1763892/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
