A likely related issue is that sometimes the display will freeze for a moment, the display will jump around like I am getting desync and then will come back fine a second or so later.

@Matt_Hartley have the same problem on Ubuntu 22.04. AFAIK both on X11 and Wayland. But it happens only when on battery.

So I haven’t had it happen to me since been waiting for it to come back for further troubleshooting.

What changed? there was a kernel update! I went from

edit:
Had problems posting and seems like it nuked my note about kernel version
Linux max-framework 6.1.0-10-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.38-1 (2023-07-14) x86_64 GNU/Linux

to

Linux max-framework 6.1.0-10-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.38-2 (2023-07-27) x86_64 GNU/Linux

(i.e. ‘6.1.38-1 (2023-07-14)’ to ‘6.1.38-2 (2023-07-27)’)

So yeah in my case the freezing was likely resolved with a kernel update.

I have had the odd graphics glitch however but I am not sure if it’s to do with the original issue or whether it’s something else.
