Testing in Zesty...

- replaced local builds of mate-panel, mate-panel-common, gir1.2-mate-panel, 
libmate-panel-applet-4-1 packages with version 1.18.1-0ubuntu2.1 from 
zesty-proposed
- set the panel background on both top and bottom panels to be transparent
- logged out and back in - no applets were crashing
- opened the properties dialog for the top panel
- moved the transparency slider very fast back and forth a few times - no 
crashes
- repeated the same test with the slider for the bottom panel - no crashes

All good, the applet crashes don't happen anymore.

Hello Buzea, or anyone else affected,

Accepted mate-panel into zesty-proposed. The package will build now and
be available at https://launchpad.net/ubuntu/+source/mate-
panel/1.18.1-0ubuntu2.1 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-zesty to verification-done-zesty. If it does not fix
the bug for you, please add a comment stating that, and change the tag
to verification-failed-zesty. In either case, details of your testing
will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Attaching the debdiff with patches to fix bug 1675888, bug 1676840, bug 1690517,
bug 1695648 for Zesty.

** Attachment added: "Debdiff for Zesty to fix 1675888, 1676840, 1690517, 
1695648"

** Description changed:

+ [Impact]
+ 
+ Almost all panel applets occasionally crash if the panel is transparent.
+ Usually it happens on session start. It affects all panels that are on the
+ screen, e.g. if you have top and bottom panels, then the applets from both
+ panels would crash.
+ 
+ The patch attached to this report fixes the issue.
+ 
+ The fix is already present in Artful and tested by developers and users.
+ Would be nice to backport it to Zesty as well, as it's really a major
+ inconvenience for users who prefer to have a transparent panel.
+ 
+ [Test Case]
+ 
+ If you see the applets crashes on session start, then the issue is already
+ reproduced. Otherwise you can try moving transparency slider in the panel
+ properties very fast back and forth - after some tries it will cause some
+ applets to crash. It's been confirmed that it's the same crash as happens
+ on session start, with the same backtrace and the same root cause.
+ 
+ [Regression Potential]
+ 
+ None. All that's done is to replace the direct call of cairo function with
+ the call to GDK's cairo support function. It proved to be the proper way to
+ do it.
+ 
+ [Other Info]
+ 
+ The patch is included into the debdiff attached to this report.
+ 
+ The debdiff contains patches to fix bug 1675888, bug 1676840, bug 1690517,
+ bug 1695648. See other reports for the corresponding SRU templates.
+ 
+ Note that the debdiff attached to bug 1690517 is a separate one for
+ Artful.
