Its ridiculously painful isn't it?
One thing that may trip you up is auto resizing. Consider disabling
it or making sure it is behaving properly.
Also, I've found generally that using custom flipped views works
better. this gives a top left co-ordinate system and avoids a lot of
jittering.
@implementation FlippedView
- (BOOL)isFlipped
{
return YES;
}
- (void)awakeFromNib;
{
for ( NSView *v in self.subviews ) {
NSRect frame = v.frame;
frame.origin.y = NSMaxY(self.bounds) - NSMaxY(frame);
v.frame = frame;
v.autoresizingMask = v.autoresizingMask ^ (NSViewMinYMargin|
NSViewMaxYMargin);
}
}
@end
Further, I never got layer backing to work properly if there are any
scroll bars involved, and there are probably other cases that simply
didn't work well (at least in Leopard).
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.
Check out MGViewAnimation from Matt Gemmell <http://mattgemmell.com/2006/11/13/mgviewanimation

Maestro to get animating/fading views and it works quite well.
Enjoy,
Peter.
