Please play these tracks in the web app, and then click in the lower left corner onto the thumbnail image of the album art. Is this blurry too?
It is not really a crossfade.
Crossfading would turn parts of the music quieter. This doesn’t happen in Plexamp. All it does is letting the current and the following track overlap. How long the overlapping goes on, depends largely on the loudness of the outro and the intro of those particular tracks.
Overlapping is automatically disabled when playing an album.
