evemu-record showing a four-finger gesture and a broken three-finger gesture
afterwards
On my ThinkPad T560, three-finger and four-finger gestures generally work fine,
however, about 50% of the time a three-finger gesture is detected as a
two-finger scroll after a four-finger gesture was used before - this is usually
fixed by doing another four-finger gesture.
I believe that this might be a kernel bug given the output of evemu-record, but
I thought I'd report it here first.
