[Bug 2067657] Re: Cursor response to touchpad sporadically becomes laggy

I have the same hardware and same issue.
I'm use ubuntu 24.10/gnome 47.

Try adding these to /etc/environment

MUTTER_DEBUG_KMS_THREAD_TYPE=user
MUTTER_DEBUG_FORCE_KMS_MODE=simple

and it still happens.

Title:
Cursor response to touchpad sporadically becomes laggy

Status in linux package in Ubuntu:
Incomplete
Status in mutter package in Ubuntu:
Incomplete

Bug description:
when using for a bit the pc, under load but sporadically, the system
slows down and appears to be some inertia to the pointer movement and
the page scroll gestures, making impossible to perform precise point
and click actions. With an external mouse does not happen, it happens
only with the trackpad. My pc specs are quite high and i just changed
thermal paste and in windows 10 it does not happen, so it's not an
hardware issue.
