The trackpad on my MacBook Air (13-inch, 2017) running 10.13.3 will occasionally register command clicks instead of normal "left" clicks after returning from sleep.
Neither command key is show as being down (verified with keyboard viewer). I used the event viewer on Karabiner-Elements to see what was happening.
The problem sometimes resolves seemingly of its own accord, other times I must restart.
I've shut down all running apps and menubar utilities, but nothing seems to effect the issue.
I'm perplexed as to what the deal is. I can't replicate the problem.
