When closing a konsole window, the process will continue running and take up 100% cpu. Reproducible: Always
Reproducible here, a bit more info: Qt: 5.4.2 KDE Frameworks: 5.13.0 Konsole: 15.08.0 on Gentoo, x86_64, shell ran by konsole is zsh.
Possibly related to (one or more of): #350475, "konsole uses 100% cpu" #344119, "100% CPU usage after closing konsole, after upgrading to 3.0.1/KF5.6.0 with nvidia driver" #343803, "Konsole keeps running in background after closing window" ?
Further, I can can confirm same behaviour on Fedora-22, using Qt 5.5.0, Konsole 15.08, and KDE Frameworks 5.15.0. I'm also using the nVidia 3.55.11 binary drivers. When closing the window via the window manager buttons, the Konsole process continues to run, and sucks up 100% CPU. Attaching to the spinning process with "gdb" and taking a quick backgrace shows me that it seems to spin in the "_nv014tls" function provided by the nVidia drivers.
