I really need something reproducible here or some pattern that we suspect. It's a bit tricky to write test cases otherwise. I suspect you're hitting one state where we don't recover correctly, but I don't quite know which one it is yet. > Regarding the typing-with-palm-off-then-palm-on scenario, I think it depends > on how quickly you put your palm on the touchpad after finishing typing.

But if the palm is put on the touchpad *immediately* after > the last keystroke, then tapping doesn't work. There's a 500ms timeout (provided 2+ key presses) after the last key event. If you put your palm down within that timeout, it'll be detected as dwt palm. After those 500ms it'll be detected based on pressure/size/whatever. I definitely put my palm down within those 500ms, if you run libinput debug-events --verbose it'll print the type of palm detection triggered.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
