Wayland lag/stuttering since kernel 6.11.2

Vanilla GNOME on Wayland Fedora 40 here, no issues (13 inch 7840U).

I do have another occasional bug that others have encountered too:

but that seems different.

Is that a “required” step to get the bug? If so which terminal?

I can’t find it now, but I vaguely remember a bug that involved the terminal emulator. I think I was running on X back then. CPU use high and/or display lag was involved. Shot in the dark but worth a mention.
