I put one finger on the touchpad and moved the other from top to bottom. This gesture is ignored. >> But if I move first finger or both, it is recognized as scrolling OK, this evemu-record is clean in term of protocol handling. It looks like the first finger is in the middle of the touchpad. Besides that I do not see any problems (and this works fine on Fedora with libinput). It must be a user-space problem. Can you tell us which distribution you are using and which driver is handling the touchpad (xorg-evdev, xorg-synaptics, xorg-libinput, wayland, mir)?
