The sensors aren't that accurate, so this causes the occasional movement. I have a patchset here that does the same 4-event averaging that xf86-input-wacom does and it seems to work fine - the patchset just needs to be tidied up more. As for which fields to use: it must be driver independent, anything else is a bug. the valuators have the highest precision but are in device units, the events_x/y have the pre-formatted coordinates relative to the window. I'd recommend those anyway because it'll make the wayland integration easier (wayland only provides the event x/y equivalents).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
