various 18.2.x mesa crashing kwin_x11; not before 18.2.x

The gpu is intel 4th gen.
I have my 2nd gen laptop which is fine with 18.2.x.
I use Arch Linux.
I've encounter the problem before.
I hesitate to open an issue because I think it'll eventually be ok after a release or next.
All of the 18.2.x is affected. But not 18.1.x line.

hi, could you please clarify the CPU model?
Comment 2 jeckferson 2018-09-27 14:25:12 UTC
CPU model is intel haswell pentium.
Comment 3 Mike Lothian 2018-09-27 15:21:46 UTC
Might be worth deleting the Mesa shader cache and the Qt shader cache

~/.cache/mesa_shader_cache
~/.cache/qtshadercache
Comment 4 jeckferson 2018-10-01 08:27:20 UTC
After the cleaning of .cache, it's going fine. Will report back after a week or two.
Comment 5 Mike Lothian 2018-10-01 08:51:14 UTC
So I think your distro uses the same build time for all their Mesa builds which means the cache is trying to reuse Mesa 18.1 shaders on Mesa 18.2

There's a fix to use the build-id on the mailing list, so hopefully this will be fixed properly soon

Occurring repeatedly with 18.2.4.
Almost every login.

It's only on my 4th gen haswell intel.
