--- Comment #78 from Michail Vourlakos <mvourla...@gmail.com> --- https://phabricator.kde.org/source/latte-dock/browse/master/app/wm/xwindowinterface.cpp$426 you can find the code from Latte handling the windowChanged signal under X11 1. Look how many checks the signals pass in order to be identified as valid 2. The last commits have added a Timer of 150ms under abstractwindowinterface in order to avoid sending a batch of signals windowChanged for the same window So the findings are the following: A. KWin is sending a batch of signals continuously even though it shouldnot B. This is happening only with that specific app C. There is the chance that this app is touching its window title all the time and KWin has no responsibility to check the Window Title is actually have changed or not D. The only interesting part would be if you could find a workaround about how plasma libtaskmanager is not hit by it... -- You are receiving this mail because: You are watching all bug changes.
