https://bugs.kde.org/show_bug.cgi?id=362208 --- Comment #4 from Marcelo Bossoni --- Notice what may be the cause: I'm currently playing Transistor game (Steam). As soon as I leave the game, that issue start to occur. Also, if I disable the compositing (Alt + Shift + F12), my taskbar shows two more tasks: Steam and Transistor game. Maybe Kwin is holding the tasks? Or at least their icons? As far as I can tell the processes are dead since there is no trace of them in ps command output. -- You are receiving this mail because: You are watching all bug changes.
