FYI: Did a fresh install on my MeCool BB2 (not pro) 2/16 (GB Ethernet) of 9.2.4.1 and problem seems to be gone. Installed all my usual CPU intensive addons- Aeon Nox Silvo, Unpause Jumpback, UpNext, etc and took long pauses on multiple videos and right now everything seems to be working fine.
I will get back if any problems pop-up, but right now even the interface (and AEON Nox Silvo is definitely a pretty CPU intensive skin) is running almost as smooth as my Odroid N2. Even bluetooth remote with my Harmony Hub is snappy.
Nice.
