Choppy / Laggy input on new hardware - rc3

Just installed Qubes 4.1 rc3 on an Intel i5 11600K with 32GB RAM and a 1TB nvme SSD.
Using integrated graphics HD730 HDMI to a 1080p monitor.

Moving the mouse looks like a slide show. There is obvious chop/input lag.

Moving between screens in the install process took 7-10 seconds per page with the page coming in 1/6th or so at a time.

Any ideas? Thanks.

Looks like the default kernel is 5.10.76-1.fc32
Have run qubes-dom0-update kernel-latest which has installed 5.4.15-1.fc32, will reboot and report back

Latest kernel solved it.
