I'm trying to get my CAGradientLayers, that i'm using to create nice gradient backgrounds, to resize nicely on rotation and modal view presentation, but they will not play ball.

Here is a video I just created showing my problem: Notice the tearing on rotation.

Also please note this video was created by filming the iPhone Simulator on OS X. I have slowed down the animations in the video to highlight my issue.

Video of Problem...

Here is an Xcode project which I just created (which is the source for the app shown in the video), basically as illustrated the issue occurs on rotation and especially when views are presented modally:

Xcode Project, modally presenting views with CAGradientLayer backgrounds...

For what it's worth I understand that using:

    [[self view] setBackgroundColor:[UIColor blackColor]];

does a reasonable job of making the transitions a bit more seamless and less jarring, but if you look at the video when I, whilst currently in landscape mode, modally present a view, you will see why the above code will not help.

Any ideas what I can do to sort this out?
