Terrible video quality

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) :wink:

A bit more clearer of the meaning of Migration. :innocent:
