Emerald: Sometimes all Emerald buttons disappear when restoring a maximized window, sometimes the restored window decoration appears to be unfocused

[MC Return]

To reproduce: Open any window -> maximize it -> restore it -> Emerald buttons are functional but hidden, sometimes window decoration is drawn like it would be unfocused

Repeat this several times, if the buttons are visible after restore.
This bug does not always show itself.

Workaround: Roll up/down the window or resize it horizontally to make the buttons reappear.

Workaround for the unfocused window deco: Select another window before re-selecting the unfocused one to make the focus return.

Invalid. Emerald is not part of the compiz project in Launchpad. If it is in Launchpad then please reassign to the correct project.

This is actually a "Decor plugin" Compiz bug.
It was fixed in Compiz trunk for some time already as this revision seemed to fully fix the problem:

http://bazaar.launchpad.net/~compiz-team/compiz/0.9.10/revision/3728

But it got reverted due to some other problems, so I am subscribing Compiz to this bug report and will close it once "Decor" finally stops misbehaving...

Unfortunately this is still happening, when running Emerald + Compiz trunk + Unity.

I am quite sure now that the problem is hidden somewhere in the Compiz decor plugin, as changes there made the bug disappear for a while, but unfortunately it is back now...

Info: The now reverted Compiz r3728 fixed the disappearing button bug almost completely, now it is back with r3751 and it is worse than ever before... :(

This further regressed. :(
The buttons are now always missing... :(
