Leopard 10.5.1 And redraws

  • I have a new iMac with an ATI,RadeonHD2600 chipset and have upgraded
    to OSX 10.5.1 including the Radeon firmware fix.

    Since upgrading I now notice that when I dismiss a dialog (modal or
    child) then the window underneath does a messy redraw. The window
    underneath displays white or blue rectangular holes which are
    refreshed slowly. I'd guess it takes about 50 ms for the redraw - it
    looks very untidy.

    Has anyone else noticed this. Is this a result of the firmware fix ?

    So far I have only noticed this problem when using my own application.

  • Have you experimented with the old standby, Quartz Debug, at all?

    I have noticed this with my Carbon CG app, too. I posted a while back
    to Carbon-dev, but got no response.

    I have not tried Quartz Debug.

    I should also add: I saw this in 10.5.0

    I have a bunch of stickies open over my desktop. When some application
    open a window, I can see a brief updating artifact around the stickies. I
    don't want to jump to conclusions too quickly, but it looks like only
    Carbon apps do that (a simple test with the Cocoa project template and the
    Carbon project template seems to confirm this).

    FWIW, this is a MBP with GF8600.

    In my case, I have a desktop-sized window that updates every 5
    seconds, in the Desktop layer (group?) so that it appears behind
    finder Desktop icons and in front of the Desktop Picture.

    If I have a lot of windows covering a portion of it for long enough,
    revealing the desktop (either by closing the window(s) or expose-ing)
    results in a grey or blue (or possibly the desktop image; I'm not
    sure) rectangle that then gets filled in an instant later. The key is
    that a portion of my window has to remain obscured for some period of
    time; trying again immediately after does not reproduce the behavior.

    It might also have to do with the initial draw, after launching. In
    that instance, the system may be deciding that that part of the window
    can never be visible, and so nothing draws there. However, my draw
    operation does not clip to anything but the full content view.
