Thanks for your quick response. Here are the steps to reproduce the problem, I also attach screenshots for the sake of clarity.
1. I'll begin with clean desktop. No application is opened. Show Desktop launcher is colored purple. See Screenshot1.png 2. Next, I open Google Chrome. See Screenshot2.png 3. Click Show Desktop icon, now Google Chrome is minimized, and the Show Desktop launcher turns black. See Screenshot3. So far so good. 4. Click the Google Chrome launcher, Google Chrome reappeared. But now, the Show Desktop launcher still in black color and from now on clicking Show Desktop launcher won't minimize all opened program as it is supposed to do. ** Attachment added: "Screenshot1.png" https://bugs.launchpad.net/ubuntu/+source/cairo-dock/+bug/1311189/+attachment/4094442/+files/Screenshot1.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311189 Title: Cairo-dock buggy show desktop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cairo-dock/+bug/1311189/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
