well, yes, that's expected :)
the code is based on detecting an overly fast movement that usually indicates
some jump in the tracking. You can force this to occur, but it wouldn't be
normal interaction with the system. The main question is whether you still see
this in normal use.

also note that when the error message appears, it means libinput has detected
the jump and discarded it, so you don't actually get a visible jump of the
cursor. From how I read the original comment, you were getting actual jumps,
not just the error message, right? at least the jumps should be gone now.
