Comment 3 for bug 182288

Confirming due to comments. I have a few machines here with Intel, NVidia, and ATI graphics cards and I have been able to get the kwin effects working on all of them. I have only experienced this type of issue with the ATI card and not having it properly configured in order to do the compositing. Doesn't KDE 4 tell you now that your system doesn't support the compositing if you attempt to enable it in the settings?
