--- Comment #7 from Martin Flöser <mgraess...@kde.org> --- >From the description it sounds that window gets mapped without the WM_TRANSIENT_FOR property and KWin and likewise XFWM does not support changing the state of that property. I just checked ICCCM and could not find anything regarding whether it is allowed or disallowed to change that property once the window is mapped. In my opinion it doesn't make sense to change it once it is mapped. At least I cannot imagine how a window manager should handle this property change once the window is mapped. If you are able to monitor the property states once the window gets mapped and then monitor for changes of the property we know more. -- You are receiving this mail because: You are watching all bug changes.
