Just an update on this issue...
Everything looked fine in the console when I enabled that debug
switch. However, I've sidestepped the issue and created an alternate
implementation that does not flicker. Drawing manually in a CALayer
had other challenges, such as not doing synchronized drawi

This might be a stupid question, but the person who is building
against your framework is using a debug version as opposed to a
release version, correct?

The call is done with click on a toolbar item, so it's not in a thread.
With the copying and releasing m_image thing you are right. Your way
is better. Thanks

I believe it would be more difficult to implement true support for a

Off hand I'm not sure of any sample code, but if you're using the

documentation for the NSMatrix class.

The "rect" arguments is not you whole frame. This is only the rect

If you want to fill you view using a rounded rect, so you have to use
