....something like this has been reported, but questions from me about it lead to, well, nothing. So, no opportunity to solve it.
?????? I was hoping that you solved it in version y8!
setting: unattended/show back/wallpaper
after <play>-command: sometimes i see the wallpaper from the session before during the first track
second track and further all works ok
Until y5, wallpaper was working ok
Suggestions: Delete old wallpaper after a <clear>-command!
Can you force show wallpaper first, before play? (is that possible?)
