Hi, I upgraded from 3.3 to 3.4 recently and found that my custom WPS does not work anymore.
Basically, my custom WPS makes use of several viewports in order to frame the AlbumArt (rounded corners) and to print the song title across the AlbumArt (thus achieving bigger AA). See screenshots attached: left side = works as intended, right side = broken.
It seems to me that at some point between the two releases, AlbumArt is refreshed frequently while before it was only rendered once per song.
I couldn't find a way to rescue my theme as no matter where I place the %C tag within the WPS it will always overlay any other parts of the layout.
