In the QuickDraw solution I used EraseRect to clear the background (now
commented out) and I replaced it with it's Quartz counter part
CGContextClearRect. With the described result. How can I get back my
window's normal background instead of just black?

You need to fill the context with white:

CGContextSetRGBFillColor( context, 1, 1, 1, 1 );
CGContextFillRect( context, cgrect );

PS in the documentation of EraseRect it says: "Using the patCopy pattern
....". Is there a Quartz equivalent for that?

There's no direct equivalent.
