--- Comment #29 from StructureDr <nic.brooke.nz at gmail.com> ---
Just a few comments in case it helps.  I run Manjaro KDE - currently Plasma
5.3.2-2 64 bit.

I started seeing these segmentation issues about a month ago - seemed to
coincide with a Plasma update so initially blamed that.  Was also running an
older kernel (3.18), and wondered about that to.

Recently switched to kernel 4.1 - this made no difference.

As suggested by others, switching to UXA mode solved the problem, but graphics
performance (Haswell i5) was unacceptable.

Last night started progressively downgrading mesa and xf86-video-intel in
various combinations.  Cross fingers I have stable behavior now - having
dropped to:

               mesa 10.5.7-1 
               xf86-video-intel 2.99.917-5.  

My testing wasn't extensive, but switching to either of these on their own did
not seem to solve the problem - only downgrading both packages.
