--- Comment #5 from madc...@atlas.cz --- I got it to happen again. It does not appear to be connected to (dis)connections of displays but to changes of display modes in general. I managed to trigger the issue twice by resuming the laptop from sleep, hooking the screen up, waiting for it to light up and *then* unlocking the session. In those cases, one of my windows was placed at (0,0) coordinates of the bounding rectangle of my display space. Since that's outside of what my displays show, the window was invisible (my display config is on the attached screenshot). I could tell what the window's position was by looking at the preview of window positions on the virtual desktops widget. Another time it happened when I switched the resolution of my external screen. In that case, one window got moved somewhere to the bottom right of my display space and I couldn't even see its position on the virtual desktops widget. In all cases I could eventually pull the window back into view. I have been using RC1 for about one day and this has happened about 5 or 6 times now. I'm, therefore, sure that I would have noticed this if it was happening before RC1. -- You are receiving this mail because: You are watching all bug changes.
