Greetings.
I recently changed a window of mine from "Buffered" to "Retained",
using the option in Interface Builder. There now seem to be display
blemishes associated with the window -- and I don't think it's my code
doing it, because the blemishes are in or on the window frame.
Blemish #1: the rounded corners of the window frame, on the top edge of
the window, have small black regions sticking out from them, as if to
"complete" the window's rectangle.
Blemish #2: the window's title bar does not refresh properly. When
another window has been covering the bar, and is then removed, the
bar's exposed portion is redrawn in dark gray, and the red/yellow/green
buttons are drawn as if they are inactive (though they still work as
expected). The bar redraws fully and correctly when the window is
brought to the front.
Am I misunderstanding how to manage retained windows? Do I need to
change something else in my application? Or is this a bug in the OS?
Can anyone replicate this?
My environment is MacOS 10.2, and the July Dev Tools that came with it.
Thanks much for any insight.
-- Colin K.
