Apache OpenOffice (AOO) Bugzilla – Issue 110060
Update notification causes flickering of application window
Last modified: 2013-01-29 21:40:14 UTC
The update notification icon causes flickering of the application window. When there is an update available, you get the update notification icon in the menu bar on the top right corner of the application window. This icon appears/disappears, if the window gets/looses the window focus. With the notification icon the menu bar needs one pixel more of height, than it needs without the notification icon. This means, that the menu bar becomes a different size, when the application window gets/looses the focus. As a result the whole application window flickers, when it gets/looses the focus. See the screenshots attached. Screenshot 1: There are two OOo application windows. The right one has the focus. It shows the update notification icon. As soon as one clicks on the left window, the update notification icon will disappear in the right window an will appear in the left window. The menu bar in the right window will become smaller by one pixel. This causes the window flicker. As well as the left window. The menu bar in the left window will become bigger by one pixel. This causes the window flicker as well. Screenshot 2: Comparison of height of the menu bar with/without update notification icon. Difference: 1 pixel. Found this bug in OOo 3.1.1 and higher on Windows 2000.
