Summary:
I have a gif  that I want to show animated. It works fine as long the NSImageView or any of its superviews isn't layer backed.

as soon as there is a layer backed view in its path, it stops animating. The only workaround I found is setting canDrawSubviewsIntoLayer=YES

Steps to Reproduce:
Add a NSImageView with an animated gif inside a layer backed supview

Expected Results:
see it animate the gif

Actual Results:
see it won't animate the gif (except if I now set canDrawSubviewsIntoLayer=YES)

Notes:
workaround is to set canDrawSubviewsIntoLayer=YES on the image view.... which feels wrong :D

    NSImageView *view = [[NSImageView alloc] initWithFrame:CGRectMake(10, 10, 50, 50)];
    view.imageScaling = NSImageScaleNone;
    view.animates = YES;
    view.image = [NSImage imageNamed:@"FanBlades2_42x42.gif"];
    view.canDrawSubviewsIntoLayer = YES;
    
    NSView *layerview = [[NSView alloc] initWithFrame:CGRectMake(0, 0, 60, 60)];
    layerview.wantsLayer = YES;
    [layerview addSubview:view];
    
    [self.window.contentView addSubview:layerview];
