Apple Magic trackpad 2 sometimes has a delayed response.
I'm using my Magic Trackpad 2 with 10.11.1 on a Late 2014 5k Retina iMac. Sometimes I notice the pointer doesn't respond for a split second when I swipe along the trackpad. This usually occurs after using a multiple finger gesture. I used thematic trackpad with no issues, but the new one just appears even once in a while to not respond for a split second.
