Same issues here - or at least somewhat relating.
Macbook pro 2015 - intense CPU & therefore battery usage (lots of heat!) from control agent service/task when operating a remote access PC.
Even when un-focused the usage remains maximum.
Eventually crashes most of the time too.
Only thing that helps is manually clicking to minimise - just unfocusing is not enough to drop resources.
Still though, all usage is far too high. Logmein never used to do this.
