After double checking that my screen refresh rate was set to 144Hz in the plasma display configuration in settings I realized that my mouse would sometimes feel smooth and other times feel laggy again (sub 60Hz maybe even). The pattern was somewhat random but it would switch from a high refresh late to a lower one quite often. Dragging a window around the screen would also yield the same effect, sometimes it feels smooth other times its much laggier. After looking around I found a post on nvidia's forums describing the same issues I was having: https://forums.developer.nvidia.com/t/545-driver-desktop-framerate-alternates-between-120-and-60-fps/271602 Nvidia has also acknowledge this issue and was able to reproduce it internally, however most if not all the users on this thread are reporting the issue while running X11, while for my part the issue is also happening on wayland and is not limited to X11. I should also note that I am only using the external monitor and have my laptop lid closed but I also tried having both screens running and the issue still remains [system] Dell XPS 17 9720, intel core i9 12900HK, RTX 3060 6GB + intel iris Xe Kubuntu 23.10 using wayland with plasma 5.27.8 nvidia driver: 545.29.02 (proprietary). uname -r: 6.5.0-10-generic Monitor: Cooler Master GM27-FQSA (connected to the laptop using the usb-c to HDMI adapter provided by Dell with the laptop) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-545/+bug/2043212/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
