I was having this exact problem with my Matlab icon. It was working at the begining without a problem, until one day the icon became invisible. I resetted the unity setting using:
gconftool-2 --recursive-unset /apps/compiz-1 After logging out and back in, I fixed my unity settings the way I wanted them and the icon was there again. I hope this can help anybody that is working on a fix to the problem. -- 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/unity/+bug/772986/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
