Installed Leia yesterday morning. No problem yet, but also I haven't usedd addons, just regular playback with wrapper. No pain. We'll see.
LATER EDIT. No dice, bad luck continues. Kodi keeps shuting and stopping after video playback start, exactly like before.
So CRASH-CRASH-CRASH. Abandon Leia.
Uninstalled Leia and reinstalled Krypton 17.6, butter-smooth.
So much for launching final releases of unfinished applications, they didn't pay attention to users' complains and reporting. Boooo....
Bye and out: Krypton user here.
