I did plan to switch to libinput in the futur, but:

I did test the xinput events and I get for a reasonable mouse motion speed an
update of coords for each column of the screen (full hd).

It means that the cursor is supposely displayed for nearly all columns of the
screen. For a fast mouse motion, the coord updates jump to a few tens of
pixels.  (1000Hz mouse)

Those numbers does not change from 60Hz to 144Hz, then I can rule out the input
code.

If it's not my eyes or the screen itself, the pb will be in the cursor update
code path from the xserver down to the driver...

The bottom of it is if I happened to see a system which has mouse motion which
looks smooth for my eyes at 60Hz, I would get back to you on this issue.

regards,
