So with the OSMC updates as of today, still seeing 18-20% CPU on the main menu, and 6-7% when on a submenu.
So on my music-only headless RPi3 I’m saving a few watts & degrees with a cronjob. Reason is, the build is headless but touching a softkey in the android remote control (yatse) can land you in the main menu and OSMC will stay there till further notice… this cronjob ensures the issue always goes away after a few minutes.
#! /bin/bash
# execute this script with crontab

# This script is a workaround to the "OSMC bug - High CPU issue with the Kodi process"
# As of Kodi 17.5, OSMC with Kodi idle and the GUI on the Main Menu consumes 20% CPU on RPi3
# By changing the GUI to any sub-menu such as Music, CPU decreases to 6% and temperature decreases
# a few degrees
