The total time is ca 80ms and well within the tap timeout threshold. The movement is within a few device units, so that threshold doesn't trigger either. And the next event comes ca 150ms after the release, so we can't even do a 'lookahead' to see if we have a busted event sequence. The same applies to the sequence at 20.648695. Now, there is relatively little we can do but one thing I noticed is that the pressure defaults are different to what the touchpad sends. So what I'll need from you is a touchpad recording that's several hours long with a lot of interaction. That should give me enough information regarding pressure values for libinput 1.7 and with a bit of luck that may also fix some of this bug.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
