Eyal,
I don’t have an answer for you, just a request for clarification. If a view has a low alpha setting, you expect the content behind it to show through, so your description sounds like normal behavior. However, I suspect you’re dealing with a real problem.
Are you saying that your view with low alpha is above other content in your app, but instead of the information which *should* show through, Yosemite is blending with other content—content from windows or the desktop behind your app?

Hi,
I'm working on a custom view. I'm using the following code to draw the view
[[NSColor colorWithDeviceRed:(float)42/255
green:(float)49/255
blue:(float)58/255
alpha:0.5] set];
NSRectFill([self bounds]);
[[NSColor colorWithDeviceRed:(float)242/255
green:(float)110/255
blue:(float)80/255
alpha:1.0] set];
NSFrameRect([self bounds]);
For some reason the view is showing through the windows/desktop behind the window where my view is located.
Surly this is a manifestation of one of the (somewhat unwanted IMO) features of Yosemite but I've not been able to find where I can opt out of this.
The window I'm drawing to is a custom window, if that matters
TIA
