Alexandre is using the same version in Debian and apparently doesn't see that problem. Probably it's worth to report a bug to FC/Metacity developers.
Please note that, at least for some applications, it might take a few window manipulations, including all of resize/minimize/restore in order to trigger the bug. So Alexandre might not be trying hard enough.
