Doh!

Sorry!  Ugh. Development systems...

My latest AMDGPU-PRO OpenCL (amdgpu-pro-18.30-635379-sle-12.tar.xz)
installation broad me

/opt/amdgpu/lib64/

but the screen corruption appeared first around Aug 22, 2018.

So it worked 'halfway' with upstream _and_ AMDGPU-PRO libdrm.

Maybe the AMD developers could include a 'tag' or something like that to
differentiate both version?!

CONCLUSION

After deleting /opt/amdgpu/lib64/ ALL is fine, again.
