** Description changed: Binary package hint: unity On 2 separate machines w/ updated as of 1/28 - On rare occasions a window will open in the top left corner with top deco buried. The most likely for this to happen is a utility window like update manager. After pulling back down into the desktop (Alt+click) it may or may not show some graphical distortion (window split in 2 parts), if so it returns to normal if opening any other window. What does appear to happen is an invisible window is created in the area where it was pulled down to, this only happens on the current workspace, any others are unaffected Attached xwininfo - first shows on affected workspace, 2nd when switching to another and clicking in same spot Note that this does not always happen, I'm thinking the 'buried' window may need to show some distorttion, not sure yet ### IMPORTANT ### - This can cause the central area of the screen (where the Alt-Tab switcher is drawn) to be unclickable. This also happens on Classic desktop. - - ### REPRODUCTION STEPS (thanks to glennric) ### - 1. Log in - 2. Open a terminal and move it away from the center of the screen where the switcher will appear. Make sure that it still has focus. - 3. Hold down Alt-Tab to activate and show the switcher. Sometimes you need to call the switcher twice. - 4. While the switcher is still visible move the mouse to a point right above the very bottom of the gray switcher window (it should be window titles area, not thumbnails area, within 1-5 pixels of the bottom is sufficient) - 5. Click there. You will see that the desktop does not take focus, and the terminal window still has focus. If you run xwininfo you can click at that location and you will see information about a window that you can't see, and that is definitely not the background nautilus window. + This can cause some areas of the screen to be unclickable. This also happens on Classic desktop.
