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

Thu Sep 1 00:57:44 UTC 2016

Package: libgtk-3-0
Version: 3.20.9-1
Severity: normal

On three pc of mine i had to downgrade the following libraries to have a
functioning desktop:
libgail-3-0
libgtk-3-0
libgtk-3-bin

Up to version 3.20.9-1 all were fine but with 3.21.5-1 and 3.21.5-2 i
had so many issues that i had to find a way to come back to a previous
state.
These are the issue i can document, but certainly there are others:
- caja (file manager) doesn't start at all.
- desktop fonts look ugly, like there isn't any antialias.
- desktop doesn't repaint correctly: if you move an icon, the older is
  still there.
- mate terminal crash if you try to change color settings.

Journalctl reports tons of entries like those, indeed belonging to
applets that updates their visualization frequently:

------------------

The same issues happened on four different machine, with different
gtk theme, adwaita included: a 686, a 686-pae, two amd64.
On one of them i've installed a fresh Mate Desktop, so i think we could
say that the problem is always reproducible. You can try: i've just
installed task-mate-desktop, without any recommended or suggested packages.

I don't know what other infos i can provide.
I've kept a 686 PC with the broken libraries available in case you need
more infos or in case you want me to make some tests.
