  • Closed Preview windows stay visible in Mission Control / Exposé

  • BugsDesktopDone

After closing a Preview window, it continues to appear in Mission Control:

While no window nor window title is visible, it is clear that this is a Preview window, because scrolling on the Orion window icon (after enabling the “Scroll to open” feature by executing defaults write com.apple.dock scroll-to-open -bool true in a terminal) reveals this the title of the preview window:

Interestingly, it doesn’t appear when right clicking the icon and clicking the “Show all Windows” menu item. Furthermore, the Preview window is only visible in Mission Control when no actual Orion windows are currently open (that is, all windows need to be either closed or miniaturized for the bug to occur).

I expect closed Preview windows to disappear and not be present in Mission Control or the “Show All Windows” user interface.

    ThePC007 Please check on latest version of Orion and post exact steps to reproduce.

        I can reproduce or produce this bug on the latest RC:

        1. Close all regular Orion browser windows
        2. Open a preview window from a link in an external app, then close it
        3. Can see the Orion RC app icon and title in Mission Control, as description in the original post
