I have encountered this problem as well on the Core with Krypton builds using various skins including the default Estuary skin. The Kodi UI becomes very unresponsive after sitting idle for random periods of time. Interestingly, a restart of Kodi doesn't correct the problem, a reboot of the Core is required.
Yes, same thing happened here. I had to reboot

We believe there is a memory leak in Amlogic builds as we see OOM issues on several devices (and sooner on ones with 1GB RAM) but we haven't been able to pin down the cause yet. No guarantees that's the issue though. I'm also conscious the 3.10 kernel used on older WeTek devices like the Core hasn't had quite the same level of developer love as the 3.14 kernel.
Is there a way we can provide more specific feedback so you can more easily pinpoint the issue?
Or maybe there is a way to use the 3.14 kernel for the Core?
Thank you!
