<pre>For the last several weeks, my Microsoft (wireless) All-in-One Media Keyboard
has required a triple-tap on the trackpad to highlight a single word of text.
It only used to need a double-tap (as you'd expect), so I know this is a fairly
recent bug.
It has nothing to do with my desktop environment (KDE), as the problem
occurs in LXDE too. Both run on X, BTW: I don't use Wayland yet. I have
obviously tested it using different applications (i.e. not just my web browser)
as well.
It's important to note that it only happens with tapping (i.e. not
clicking). If I double-click on the same part of the trackpad, the
word is highlighted as expected. However, if I instead double-tap,
nothing happens.
The relevant output from the "usb-devices" command is as follows:
T: Bus=02 Lev=01 Prnt=01 Port=11 Cnt=01 Dev#= 5 Spd=12 MxCh= 0

I originally reported this bug to the 'linux-usb' mailing list. They suggested
it might instead be a 'libinput' problem, which it is. After issuing
"downgrade libinput" (on Arch Linux), choosing v1.8.3, and relaunching X, the
problem went away.
Jumping (back) up to v1.9.1 (or newer) made it reappear. This means the
offending section of code was incorporated somewhere between those versions.
Let me know if you need me to narrow it down further. I'm happy to run more
tests and/or supply additional information.</pre>
