-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 GWorkspace: focus change between any.app and Gworksapce/Desktop causes weird flickering I thought someone mentioned this, but I couldn't find the previous email to respond to, properly. Anyways, switching between, for e.g., GNUMail.app and Terminal.app does not make this happen, but clicking on the "Desktop" (Desktop feature turned on) causes, what seems, to be all underlying windows breifly appearing, and then a screen "flash". What is odd, is that I cannot reliably recreate this bug when I have 1 GWorkspace browser window open as well, although it happens "sometimes." Has any one else seen this? Any work-arounds? (Honestly, I'd appreciate it -- the flashing is giving me a headache).
The borderless window containing the desktop view must become the main window when you click on it. But, beeing it at NSDesktopWindowLevel, this works only with this hack: the -mouseDown: method of the view sends a -makeKeyWindow to its window; doing this, the window become the first responder but it is also ordered in front of the other windows; to avoid this, the window's -orderWindow:relativeTo: method has these two lines: [super orderWindow: place relativeTo: otherWin]; // let the window get the events [self setLevel: NSDesktopWindowLevel]; // put it again at its level And here you see the flicker. I think that this problem should be fixed (in -back, probably) treating differently from the other cases the case of a window at NSDesktopWindowLevel that must become the main window.
