Thanks, got a lot of community effort this time round. The album track list was something we introduced in the last release, 4.1.0, that caused albums to display multi disc tracks all goofy, screenshots -> https://github.com/eddyizm/tempus/issues/234
It was in effort to improve performance and deal with lag/large libraries. We will have to go back and figure it out.
I believe there is a ticket for what you are describing?
Several performance issues addressed and bug fixes applied.
