I've also run into this issue on Pop!_OS 20.04 LTS; Nvidia driver 450.66; Linux kernel 5.4.0-7642-generic; GeForce GTX 1080 8GB; mutter 3.36.4; GNOME Shell 3.36.4.
I'm running two monitors: NS-PMG278 (144Hz DP connection) + Dell U2719D (60Hz DP connection), both at 1440x2560. I'm getting the exact same symptoms as seppel. Updating /etc/environment with __GL_SYNC_DISPLAY_DEVICE doesn't seem to help either. -- 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/nvidia-graphics-drivers-418/+bug/1820832/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
