It seems I'm not the only one with this issue as I recently found this issue 
(https://bugzilla.kernel.org/show_bug.cgi?id=195225) in the kernel bug 
tracker. It looks like dual shock 4 controllers have a similar issue.

I asked on IRC and someone recommended to ping this message. Again, I would 
appreciate some comments on this issue and it would be great if this issue 
could be fixed.
