"Show desktop" makes windows decorations unusable

[eden6000]

How to reproduce:
1. open 3 programs;
2. iconize 2 of them;
3. apply show-desktop via ctrl-alt-d (twice, due to bug #878057), so the third window iconizes as well;
4. unminimize one of the 2 windows as of point 2.

you'll see its top bar is unclickable, so you can't move it, nor minimize, close or maximize.

Supposed this bug is reported correctly, I don't understand why it gets no audience....it seems to me a severe bug, since you find yourself without control on the windows, try to explain to a newbie how to solve it...bah, this is strange...

Hi, eden6000, this bug was already reported. Sorry that you had no audience. We have lots of reports to go through. I'm going to mark this bug as a duplicate of the other one.

You will be happy to know that this issue is fixed. Make sure your computer is up to date and the issue will be gone. Thanks for your patience.

Thanks for your reply Chauncellor...I'm sorry, it was me that had to mark this bug as solved and as a duplicate of #880449. Infact I commented that bug, helping an user to upgrade to unity 5.12, that is where the bug is solved.
Thanks and sorry again.
