Comment #7 shows the wrong driver in use - it's using software rendering on the CPU instead of using the GPU. I cannot figure out why yet, but generally recommend you use long term support release 22.04 instead: https://ubuntu.com/download/desktop ** Changed in: linux-hwe-5.13 (Ubuntu)

In that case it sounds like a driver bug. Firstly please check you're not using the deprecated 'intel' Xorg driver. It should be the 'modesetting' driver, although the attached logs suggest you're already using that. Secondly try live booting a newer Ubuntu release and tell us if it has the same
