I have a S905X3 device (X96Max) with a Sony Bravia TV. The problem is that I have green color lines in the up and right borders: https://imgur.com/a/QqA5NU2
In the previous CE versions, I enable the “Use 4:2:2 colour subsampling” option and the problems goes, but with the last version (9.2.5) it is not working.
It only happens with my TV, I have same devices with different TVs and works perfect.
It just looks like it needs calibrating, possibly by adjust the ‘Overscan’ setting on your TV (I think Sony call it ‘Full Pixel’). Failing that you could adjust it in Kodi (Interface/Skin/Zoom), but the TV ‘Full Pixel’ Setting would be the best solution.
