So no mesa is installed.  Should that be the issue?

This seems to be up to date.

Currently I have

beignet-opencl-icd:
  Installed: 1.0.3+dfsg-1~bpo8+1
  Candidate: 1.0.3+dfsg-1~bpo8+1
  Version table:
     1.1.2-2 0

        501 http://ftp.de.debian.org/debian/ jessie-backports/main amd64 Packages
        100 /var/lib/dpkg/status

BTW, I was able to reproduce the graphics-scrambled issue after calling
phyml which is using libhmsbeagle:

 $ LC_ALL=C apt-cache policy libhmsbeagle1
libhmsbeagle1:
  Installed: 2.1.2+20150609-1~bpo8+1
  Candidate: 2.1.2+20150609-1~bpo8+1
  Version table:

        100 /var/lib/dpkg/status
     2.1.2-1 0
        500 http://httpredir.debian.org/debian/ jessie/main amd64 Packages

My attempt to backport the latest libhmsbeagle to Jessie just failed and
I suspect some issue with beignet as well.  I need to track this down more
deeply, thought.

I can confirm that after purging purge beignet-opencl-icd (which also
removed linux-image-4.4.0-0.bpo.1-amd64 - which is IMHO a bit strange
but does not affect me since 4.5.0 kernel is installed - so just
reporting) the graphics issue vanished (for both cases localc and phyml).
So I can now work normaly - just without beignet-opencl-icd.

I'll check this later today (please kindly ping again if I get
distractec again ;-))
 
Thanks a lot for your very helpful input
