I'm getting a possibly similar bug.
Lately, during the first couple of minutes after login, I'm getting terrible mouse freezes every two seconds:
Here is a truncated sample:

The recurrent UnloadModule: "libinput" is the symptom that cause mouse freezes.
I didn't find a similar bug so far.

The behavior is noticeable during boot, but it also occasionally happens later during a typical day.
