Unfortunately, this does not fix it for me yet. I think the bug is changing in nature, but it is still not where things before 1.8 (778) was released.
There are a few inconsistencies remaining which may or may not be caused by the same bug.
Let me start with an obvious one, which I am not sure how to best trouble-shoot. “Giuseppe Verdi” shows up in my artist list although he is not “linked artist” for any album. See screenshot below. Beethoven also has albums as composer, but he (rightfully) does not show up under the album view as he isn’t linked artist for any album.
