unity launcher wrong behaviour with _NET_WM_STRUT in another app

[Dennis Schwertel]

Hi
i wrote a little panel for my touchpad. this a hack but did reveal a bug in unity:
https://gist.github.com/1329168
this script creates a panel at the bottom of the screen and injects onboard (the onscreen keyboard) into it. now the keyboard is always visible even when windows are maximized because windows do not go over or under this panel.

this works fine in unity-2d and all the windows and the launcher stays above this area. But in unity-3d, the launcher does not react to this "resize" event and the launcher still uses the complete space even if it should resize. unity-2d does this correct.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?

This will help us to find and resolve the problem.

use this script to create a bottom panel with a keyboard injected into it.

the other steps are in the description.

the important part is the x window property change _NET_WM_STRUT which is kinda broken in the launcher of unity 3d because it does not honor this property

just tried it in ubuntu precise (up to date patches) and 11.10. This problem still occurs when launching the script.

If you're going to use onboard anyway, shouldn't onboard work well with Unity when enabled with 12.04 onward?

I have attached your code here for ease. I have been able to create the issue here as well. I believe compiz people would know better.
