Just confirming that this issue affects me also. Here's my post from the other other bug:
I'm using Xorg with an AMD Vega 64. Both displays are connected to the GPU. My main 144hz display is connected via Display Port, and my second 60hz display is connected via HDMI. I'm using Mesa 19.1.0-devel - padoka PPA When I perform the test case in the first post, I get high framerates when the secondary display is disabled, and only 60 fps when it's enabled. -- 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/gnome-shell/+bug/1820832/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
