I believe it is due to the resource-saving moving of the pixels in
your view that is by default used by the OS to minimize the amount
of re-drawing that must be done.
You can force the OS to redraw your view each time it scrolls which
should solve your issue by using the setCopiesOnScroll: method of
the NSClipView that contains your NSScrollView. I'm a newbie myself
and I just discovered this last week, so if I'm wrong, someone
please slap me.
the time is not (supposed to) be shown in my custom view. I have 2
text fields above that view for the time (one for the system's time
zone, the other for GMT) and they are the ones that get blurred. but
it just occurred to me that i could remove the call to the doTime
method from the drawRect method in which case the doTime method would
only be called by the timer which would be sufficient.
hmm... when I move a slider, the doTime method gets called several
times a second. is it possible that something stumbles over its own
feet trying to keep up with all the calls, thereby causing the blurring?
