There are two touches in this one that trigger event sequence B as shown in the graphic here: <a href="https://wayland.freedesktop.org/libinput/doc/latest/palm_detection.html">https://wayland.freedesktop.org/libinput/doc/latest/palm_detection.html</a> There are also a few that start outside of the palm detection zones so they don't get detected as palms at all. I think widening the palm areas is a good idea here but I'm not sure how far, a quick test locally increasing it to 8% each side (which on yours would be ~8mm each side) seems to do the trick for this recording. Might need to do a few more measurements here though.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
