Konsole ~100% CPU use after closing.

[sunrat]

Konsole sometimes doesn't close properly from the window close button, seems ok from Ctrl-D. Just wondering if anyone else is experiencing this.

I seem to have several issues like this possibly since installing Nvidia GTX970 with Nvidia drivers and new 4k monitor. Also have occasional Dolphin crash, and Plasma segfault notification on waking monitor from standby (with no apparent symptoms apart from notification).
Held off d-u since  2015-11-25 until I'm sure Plasma 5.5 is safe.

Are you running sli (2 cards) with the GTX 970

This don't like right, especially the nvidia (unloaded: fbdev,vesa,nouveau) part, I could be wrong though, I've just never seen that on any of my boxes

No SLI, single GTX970. There is a newer experimental driver but yet to install.
I need to head to work now, busy for a couple of days so it will have to wait. I was just wondering if anyone else was having similar issue.
