Comment # 24 on bug 1094733 from Felipe Abrahao

(In reply to Fabian Vogt from comment #8)
> xf86-video-intel should not be used, so uninstall that again.
> 
> That it works with LIBGL_ALWAYS_SOFTWARE=1 means it's a bug in the graphics
> stack and unlikely Plasma itself, so reassigning.
> 
> Can you provide a backtrace for the software rendering crash?
