kwin fails to resize to fit to the NX window with this version of libxfixes3

[Iordan Iordanov]

We use KDE under NX, and were happy to discover that the new libxrandr proposed in this bug-report:
https://bugs.launchpad.net/ubuntu/precise/+source/libxrandr/+bug/985202

fixes the issue of kwin crashing when the NX window resizes.

However, we now discover that it does not resize to fit the NX window either when the NX window is resized. Please see the attached screenshot for an example of what happens.

However, there is a relatively easy workaround for this issue which unfortunately involves downgrading libxfixes3 to the version from Oneiric. Specifically, the package one needs to get is:
http://packages.ubuntu.com/oneiric/libxfixes3

The version numbers of the two packages are very close, so I decided to look at the diff between the sources for Oneiric and Precise, and I discovered that the only source-code difference is one patch which was added to Precise (which I'm also attaching). Something in that patch is what breaks the ability of kwin to resize to fit the NX window.

Please let me know if I can be of further assistance!

Sincerely,
Iordan

This is the patch which "upgrades" libxfixes3 from Oneiric to Precise which seems to break kwin's ability to resize.
