Hello,

Whenever I try to create a custom window using NSBorderlessWindowMask and set an NSView (for example an NSImageView) as its contentView, I get a 1px gray border around the NSView and I don't seem to be able to get rid of it.

I have followed several approaches including Apple's RoundTransparentWindow sample code as well as several suggestions on StackOverflow.

I suspect the gray border is either coming from the window itself or the NSView.

Have any of you experienced this problem or do you have a possible solution?

Thanks
