Metacity used to have the "grab server and do XOR" type of animation,
and it was changed to the current one because grabbing the server
produces temporary artifacts due to apps not handling expose events.

The code to use XOR is still in metacity/src/effects.c if you want to
try it.

A shaped window as used now is clearly slower, but no server grab.

However, if we do the animation and only then hide the window, we may
not notice the expose event problem so much. Right now it hides the
window first, so generates exposes during the server grab.
