Welcome to the Rockbox Technical Forums!
a current build simulator shows this behaviour also while seeking.
This means that I think there is indeed a bug, but the result of that bug is not that the AA is clipped while paused, it's that parts of the AA are shown at all.
....I know I'm asking the WPS to do things it's not designed for. I just hope it still can be solved with the WPS code I'm familiar with. If it's a problem with the skin enige itself, I can't do anything (which is very annoying to me)
