Comment 15 for bug 1573478

I've installed it, but it's not convenient today to logout to restart metacity.

Note that the problem with the undisplayable firefox window is probably a separate bug. I think it relates to a similar problem: I keep an xcb window at the bottom of the left screen. It has started vanishing off-screen, too. From the animations if I hide and unhide it, it appears to have dropped below the edge of the displayable area. I'm not sure what triggers it. (I thought perhaps it happens when the scfreen locks, but I just tried that and it doesn't.)

But for xcb, if I select Maximise from the dock menu for it, I can see it and use it. But there's no other way to move its window or resize it so it's back on screen. I have to kill it and restart it. If I start a fresh xcb before killing the old one, it even preserves all the cut buffers.

I've also seen firefox windows lose all their desktop decorations (re-sizing edges, top bar with minimise, maximise, close icons), but hiding and then unhiding it via the window's right-click menu in the dock reinstates all those parts of the window.
