Comment 36 for bug 1492037

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.
