Just migrated form Libreelec to CoreELEC running on a Beeline MIII Ver II.
Everything running well except for terrible video quality. When I start a 1080p stream, it looks very soft, like all the detail was lost.
I did install input video.stream to use with amazon but disabled it to see if that was the problem, but no change.
What settings do I need to fix to get back my previous picture quality?
You tried the whitelist settings ?
Migration from LE to CE is not supported.
Clean CE with fresh addon installs.
Migration is fine when using a clean CE install, manually re-entering settings and installing addons.
Upgrading is not officially supported (re-using old LE data with CE build)
A bit more clearer of the meaning of Migration.
