Graham hi,
thanks for the suggestion.
Unfortunately I cannot get it to change the original behaviour.
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
CALayer * zCALayerRoot = [CALayer layer];
zCALayerRoot.autoresizingMask = kCALayerWidthSizable | kCALayerHeightSizable;
zCALayerRoot.needsDisplayOnBoundsChange = YES;
[self.myViewObj setLayer: zCALayerRoot];
//zCALayerRoot.autoresizingMask = kCALayerWidthSizable | kCALayerHeightSizable;
//zCALayerRoot.needsDisplayOnBoundsChange = YES;
[self.myViewObj setWantsLayer:YES];
self.myViewObj.layer.backgroundColor = CGColorCreateGenericRGB(0.0,0.0,0.0,1.0);
}
