Public bug reported: Fast double-taps get treated as a single click.
Behavior is present in Ubuntu 18.04 (libinput 1.10.4-1) but not in 17.10 (libinput 1.8.2-1ubuntu2). Still present in 18.10 daily downloaded 2018.10.08 (libinput 1.12.0-1). I think this is similar to https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1762536 with different hardware. I'm trying to run Ubuntu 18.04 in a VMware Fusion guest on a Macbook host. If I double-tap the trackpad fast, it gets treated as a single- click in Ubuntu. If I double-tap slow (but not too slow) it gets treated as a double-click. Hitting the narrow window is hard! This makes it tough to run X in a VM on a Macbook. I suspect that the host hardware+software delivers a synthesized double- click to the guest, and that the time between the clicks is very small. evemu-record shows two "VirtualPS/2 VMware Virtual Mouse" devices and a "VMware VMware Virtual USB Mouse". Capture of the first of these is attached. It looks to me like the second tap comes 8 ms after the first, and I'm betting that is treated as bounce.
