I am trying to resize a window with an animation using the
NSAnimatablePropertyContainer animator proxy mechanism. The views have
the "Wants CA Layer" option set in IB.
I use this code:
NSRect frame = window.frame;
frame.size.height += delta;
frame.origin.y -= delta;
[[window animator] setFrame:frame display:YES];
The problem is that during the animation, the window contens jump down
briefly when the window grows, and up when it shrinks. It does not do
this when I do not reset the origin by commenting out this line:
// frame.origin.y -= delta;
But then the window grows upward which is not what I want.
I made a screen video here:

It also works if I don’t enable the CA layer backing in IB, but I need
that because I am going to fade a subview at the same time as I resize
the window. Without CA layers I can only hide and show the subview
with a hard transition, but I want to fade it.
Is there something I should do differently or is this a known issue?
