CALayer NSImage content does not pick the correct view

I am setting NSImages

in the content of several CALayers

. All of these images have 4 repetitions, 1x, 2x, 5x and 10x . 3 of these images seem fine when I set contentsScale when my view changes it backingScaleFactor

, but one of them seems to always select the 1x view no matter what I do. Here are my images entered the console:

The third (28 x 40) is always drawn at 1x. Here is the code I am using to set the scale factor:

- (void)viewDidChangeBackingProperties {
    [super viewDidChangeBackingProperties];
    self.layer.contentsScale       = self.window.backingScaleFactor;
    self.otherLayer.contentsScale  = self.window.backingScaleFactor;

    self.otherLayer.contents = self.image;
}

      

        
        
        
      

    

I set the content of the layer again because it was stated in this question that it CALayer

picks the best view NSImage

when drawing it and will need to be set again.

I ran a new method -recommendedLayerContentsScale:

on all of my images and they all returned 2.0 when given 2.0, except for the one that doesn't scale correctly.

EDIT: I wrote the split image to a file and then opened a new one NSImage

with - initWithContentsOfFile

in another application and I put it in NSImageView

and the problem persists! He works with one of the images that worked. Obviously there is something wrong with Apple's code selection.
