--- Comment #2 from Sven-Haegar Koch <mail-...@sdinet.de> --- As the platform of the bug says this is Debian Unstable, which at least right now still has 5.8.5. haegar@aurora:~$ kwin_x11 --replace Module 'org.kde.kwin.decoration' does not contain a module identifier directive - it cannot be protected from external registrations. kwin_core: Compositing is not possible QPainter::begin: Paint device returned engine == 0, type: 3 QPainter::setRenderHint: Painter must be active to set rendering hints QPainter::setWindow: Painter not active QPainter::setClipRect: Painter not active QPainter::begin: Paint device returned engine == 0, type: 3 QPainter::setRenderHint: Painter must be active to set rendering hints QPainter::setWindow: Painter not active QPainter::setClipRect: Painter not active Clicking on a window titlebar to move it gets the output: QXcbConnection: XCB error: 3 (BadWindow), sequence: 6086, resource id: 44119848, major code: 2 (ChangeWindowAttributes), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 7820, resource id: 67109147, major code: 18 (ChangeProperty), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 9398, resource id: 67109148, major code: 18 (ChangeProperty), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 9614, resource id: 67109149, major code: 18 (ChangeProperty), minor code: 0 Not sure that this bug does not have the same source - but as that bug is around Cluster-SSH sending invalid timestamps, which I neither use nor have installed, I decided to open a new one. -- You are receiving this mail because: You are watching all bug changes.
