I confirm I also have this bug with Spotify. If I launch from the unity panel, it often shows a blank icon. If I fully exit Spotify and launch it in the same way (from the unity bar) it then works and "merges" with the launcher.
The blank icon is clickable and does bring up Spotify. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/772986 Title: Unity launcher single missing/invisible/blank icon To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/772986/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
