I don't think it's worth attempting. I *think* that gradients are
cached in some way so trying to recalculate the gradient to span the
update rect correctly is: a) going to need a fair bit of work to
calculate and b) not allow caching to work efficiently. In any case,
pixels that are clippe
This is normally what I have to do as well, but is there a more
optimized way to achieve the goal of drawing only the rect that needs
redrawing?

possibly small rect
Check the code that draws the 1-pixel line. It should be calculating
coordinates of the line based on the view's bounds rectangle, not the
rectangle that is passed to drawRect:.

Hi All,
This is something that I haven't seen before. I have a custom view
that inherits from NSView directly and just draws a gradient
background. In IB I've placed an NSSlider on the view which works
fine. The problem comes when drawRect in my custom view is invoked, I
draw the gradient
