--- Comment #4 from Alexander Schier <a...@laxu.de> --- It gets worse. Randomly windows do not have a visible decoration at all, even when they are opened after resuming (I had at least the impression that the problem only affects windows that already were open), but I can click the buttons when I know the position. I do not see a clear pattern which windows do not work, but when I disable compositing the broken titlebars reappear as black bar, which is still clickable.
