Kodi becomes unresponsive after a little timeout

Hi
I’ve had this issue for a couple of years, and it is so bad that I recently stopped using Kodi altogether.

Whenever I leave Kodi for a while, be it while playing a movie or at home screen, the Skin becomes kinda broken and unresponsive. If I hover the mouse over anything it will not select, and sometimes even keyboard clicks won’t work.

Anyone with a similar issue?

It first started after a Mac update “Perhaps 10.9?”, and ever since I’ve tried everything, but nothing will work.
I tried disabling add-ons, I tried moving my usersdata file, I tried disabling a couple of Mac OS X features that I suspected, but nothing worked.

Any thoughts?
