If the device only have 60 and 120 Hz in the config group, 60 Hz won't be used when watching a 24 fps video and instead 120 Hz will be used because it is perfectly divisible by 24. This is a publicly documented AOSP behavior [1], but it simply does not make any practical sense and trades off significant amount of power for a very-hard-to-notice jitter-free experience. Set debug.sf.frame_rate_multiple_threshold to 60 by default to limit this behavior to 60 or lower fps.
