With regards playing music, I've noticed for the last couple of updates seem to have a minor bug in the screensaver.
I use the tagscanner script putting the year in the album title in brackets.
It used to work, and sometimes still does.
The first few songs seem to be alright, them it goes back to displaying the basic name.
Come out of screensaver, and back into it again, and it's OK for a couple of songs again.
Thanks for listening.
