--- Comment #7 from Daniel Lichtenberger <daniel.lichtenber...@gmx.net> --- Adding some debug statements to kwin pointed me towards grabXKeyboard in utils.cpp. Whenever Alt-Tabbing fails, this method returned false because XCB returns XCB_GRAB_STATUS_ALREADY_GRABBED instead of XCB_GRAB_STATUS_SUCCESS. "xdotool key XF86LogGrabInfo" lists only kwin and kglobalaccel5 grabs, so maybe some race condition with the KDE hotkey handling? Unfortunately the XCB response does not seem to include any other information that may lead to the client that is actually holding the keyboard lock (which I assume is not kwin itself, as it correctly seems to release the keyboard grab). -- You are receiving this mail because: You are watching all bug changes.
