Bug#836246: Acknowledgement (libgtk-3-0: Upgrade from 3.20.9 to 3.21.5 broke Mate desktop)

[Cesare Leonardi]

I'd like to thank Michael Biebl, the only one who was friendly, who saw 
the value in this BR and who understood the reason why i opened this 
bug: to let Debian developer know about a problem after a recent upgrade.

I'm really bewildered with those people that looks pissed off by me 
reporting about problems, blaming me to ignore how unstable works and 
telling me that i don't have to complain.
I'm not complaining about the temporarly Mate breakage (i've found a 
workaround), and i know that unstable can broke and so on. I only wanted 
do inform Debian about that and being as detailed as possible to help 
finding a solution! Including reporting the workaround, to help those 
users googling around for the same problem. It's all i can do and i 
assure you that it took time to do all that.
I don't understand: isn't it better one more bug report than a bug that 
propagate to testing or stable unnoticed?

Adrian, you said that you cannot reproduce many problems i've reported.
Please, i repeat, start a VM, install task-mate-desktop, even without 
any recommended or suggested packages, and login in lightdm. Now:
- You will see that fonts looks ugly and also icons looks strange, with 
a sort of shadows under them.
- Double click on "Computer", or your folder's home or on the trash: you 
will see that after a flash, nothing happens.
- Try to move one of the desktop's icons: you will see different 
refreshing problems, and the icons in the initial position that doesn't 
get erased. But it only a graphics artifact: the icons isn't still there 
anymore, as you can see trying clicking on it or moving, for example, a 
terminal windows on it, then moving away.

Have you tried that?

But looks like i've only lost time to investigate and report this bug. 
Feel free to do what you want with it.

Cesare.
