[RESPONDED] Framework 13th gen DIY Ubuntu - Screen super laggy (1FPS) on occasion

What do you mean by attached? It didn’t happen to occur in the few times I was using an external monitor, and I just use the touchpad, so the laptop wasn’t attached to anything (except the network in an abstract way I suppose). Edit: The laptop might have been charging at the time if that’s relevant.

So with an attached display and without, appreciate the clarification.

Two of the times, it happened when I was on a graphically-intensive website (specifically connecting to virtual table-top software that renders lighting client-side).
One of the other times it happened while I was completing a complex equation in desmos. These don’t have much in common, so I don’t know that it’s anything more than a coincidence.

I have not had success with trying to replicate this - attached display or merely internal display.

• Try booting from a current ISO of Fedora 39 (latest release copy) on a USB key. It will be an older kernel, but, it will also be a clean environment. Try the problem website there.

• If you are able to replicate it in the live environment as well, still seeing the DMUB messaging error in the logs, please file a bug report.
