That is because in "folder view" you only get landscape cards. Then inside this we can put the real image. That is the actual issue at play.
The way the Roku works you do not get to know the type of image before you set the card frame. So we use the "type" to tell which card frame to use to build the grid with. This type is folder. Not very useful.
But we do know it is folder within a movie or tv library type. We can actually display a poster frame when we know it is folder with TV/MOVIE and a square with folder and MUSIC. That is possible.
But I was told we cannot assume the folder view for movies and tv will be a poster. So we left it a landscape frame.
@Luke @ebr Should we use the poster frame when it is folder view within a movie or tv library? That would solve this issue.
Back on November 20th 2018 I made this issue:
Issue #121: Folder View is wonky .. I made this issue way back when about this problem.
Then on March 1st 2019 Luke made this issue:
Issue #263: default images based on thumbs .. Basically #263 is the same as #121.
We need to fix this problem eventually. It will wipe two open issues off the tracker. Kill two birds with one stone. Winning!
