I have the same stack in the crashing thread. I have attached a fresh
backtrace (which the crash reporting assistant says does not contain
enough information).

I use the integrated GPU of my i7-4790K CPU. Intel says it's an Intel
HD Graphics 4600 GPU.
http://ark.intel.com/fr/products/80807/Intel-Core-i7-4790K-Processor-8M-Cache-up-to-4_40-GHz
The driver is open-source and provided by xserver-xorg-video-intel
2:2.99.917+git20160218-1.
I have also run into a bunch of other issues which may or may not be
related and may point to a driver or compositor issue or other:
* When I close a window its image sometimes lingers on until I switch
focus between two windows, or erase it by moving a window around.
Note that this is not just the background not being repainted as it
also affects the windows that were behind it.
* I use Google Chrome to displays photographs, one per tab. Sometimes
switching between tabs does not completely repaint the tab, forcing
me to switch back and forth a few times to get it to work.
* I also sometimes, but quite rarely, get this when I switch between
Konsole tabs.
