After changing cell borders in Calc, Metacity stops drawing gnome-panel

[Dmitry Shachnev]

This is a very strange bug, but I can reliably reproduce it on Ubuntu 14.10 amd64 with latest updates.

Steps to reproduce:

* Log in into GNOME Flashback (Metacity) session.
* Open Libreoffice Calc.
* Click on the "Borders" item on the toolbar and select the first option.

After that, gnome-panel will be invisible. However, it is still there, and restarting Metacity makes it show again.
This does not happen when using Compiz.

See the screencast attached.

Mate has fix for this - https://github.com/mate-desktop/marco/commit/064f1ff4d56da2d0fc6b9cce674c667c5d3c7ec4

Thanks Alberts, I tested it and it fixes the issue. Will you cherry-pick it to Metacity?

[Alberts Muktupāvels (muktupavels)]

Yes, but only for 3.14 release.

[Dmitry Shachnev (mitya57)]

That doesn't matter, I will apply this patch in Ubuntu in the meantime.
