I'm not really au fait with building my own kernels, so I used the pre-built
5.4.rc7 kernel provided by the openSUSE project at
<http://download.opensuse.org/repositories/Kernel:/linux-next/standard/x86_64/>.
 Supposedly this version includes the latest (or at least a much more recent)
version of the i915 driver than the stock 4.12.14 kernel that currently ships
with openSUSE 15.1.

With this newer kernel package, I'm not able to reproduce the problem.  There's
no blinking and moreover the whole system runs noticeably faster.

So I suppose this means that whatever issue I was experiencing was fixed
between 4.12.14 and 5.4.rc7.  Is there any easy way of finding out what
specific commit fixed the issue?  If so I might be able to convince the
openSUSE kernel maintainers to apply a patch to the older version of the kernel
they're currently distributing.
