--- Comment #4 from qydwhotm...@gmail.com --- ▣The transient status bool is defined here(https://github.com/KDE/kwin/blob/8c8098a61c8990076f6d0866d662ab7980e49dc7/src/x11client.h#L559) The default value of m_transientForId is equal to XCB_WINDOW_NONE. ▣ m_transientForId is modified by setTransient(). (https://github.com/KDE/kwin/blob/c61085dc2e28cb7d737c9b049499b4433916b194/src/x11client.cpp#L2966) ▣setTransient() is called by readTransientProperty()(https://github.com/KDE/kwin/blob/c61085dc2e28cb7d737c9b049499b4433916b194/src/x11client.cpp#L2947). 1. If transientFor.getTransientFor(&new_transient_for_id) returns false, isTransient() is false. 2. If verifyTransientFor() fails, isTransient() is false. There are some debug messages defined in verifyTransientFor(), but I haven't seen them. So I guess WM_TRANSIENT_FOR is None when verifyTransientFor() fails. ▣verifyTransientFor() is defined here(https://github.com/KDE/kwin/blob/c61085dc2e28cb7d737c9b049499b4433916b194/src/x11client.cpp#L3120) More debug information is needed to find what part is wrong. -- You are receiving this mail because: You are watching all bug changes.
