I upgraded via the tar file dropped in the Updates share.
All seemed to go well initially, but at start up, I get the KODI splash screen flashing (on & off, but not quickly). Eventually I get to the main screen (but after a longish wait). Once at the main screen I can tell my settings aren't preserved (temp in C and date format is non-US), plus, many of the onscreen menu items are no longer visible on the screen, even when highlighted (maybe just a text color issue as the functionality is still there). I tried changing the Skin from Aeon Nox back to Confluence, but it's not made a difference.
All the functionality seems to be there.
I've attached a few screen shots and the output from "dmesg" in case that provides any hints.
I believe the only possibly "non-standard" thing I have is that I've moved the "Storage" data to an external USB flash drive...it worked fine w/OpenELEC so I assumed there'd be no issues with LibreELEC.
Any suggestions for a resolution would be appreciated.
I did make a System/Kodi backup prior to upgrading.
