I think Peter probably considered that already and it sounds like that might be impossible. You can't ask the person "are you trying to keep your finger still?". You can only see what the touchpad reports, and the touchpad "wobbling" with a still finger looks the same as a non-wobbly touchpad with a wobbling finger :) >From what I understand this is why the current approach does and must enable hysteresis first. And then disables it when it thinks there is no hardware "wobble". The only bug here is that the current approach is disabling hysteresis too soon by accident (only waiting for 80ms of stillness whereas it should be something like 100ms or a slightly different algorithm).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
