Comment 51 for bug 459647

@SabreWolfy: Yes, I confirm that your changes will be lost the next time the compiz-core package is updated via a normal upgrade.

To stop this you can just put the package on hold [echo "compiz-core hold" | sudo dpkg --set-selections]. You can confirm it's new state with [dpkg --get-selections | grep compiz-core]. While on hold, the package will still be displayed in update manager or in apt-get/aptitude, etc, but it won't be automatically selected. To remove the hold just do [echo "compiz-core install" | sudo dpkg --set-selections].

Alternatively you could create a diversion using dpkg-divert, but since I imagine this bug will be fixed sometime soon it's probably easier just to put it on hold until then.

@JohnathanHard: Yes, I'm also seeing VLC using the normal white-cursor instead of the themed one.
