'Minimize to tray' animation causes dialog to jump

[TenLeftFingers]

Binary package hint: compiz

What happens: When I click the minimize button on a file-transfer dialog, it jumps a few pixels upwards before the animation begins (or as part of the start of the animation). It looks quite jarring.

What I expected to happen: When I click the minimize button, the dialog should be minimized via the usual smooth animations that we are used to from compiz.

To reproduce:
1) Begin a file transfer large enough to make the dialog appear.
2) Observing the position of the dialog, click the Minimize button.
3) Notice the sudden jerk upwards of the dialog before the animation.
