--- Comment #12 from Daniel Rowe <daniel.r...@fathom13.com> ---
So I reinstalled the OpenCL package and now when I run I get the AMD GPU as the
default GPU device which is on this system as well now it runs fine. What's
annoying is why is the AMD GPU now the default and how this happen by just dnf
remove, dnf install. The system does have an intel GPU and an AMD VEGAM GPU on
the CPU (i7-8809G).
Ill have to do a bit of reading up on how to configure OpenCL and how it works.
Must be able to select the device some how.
So this is really a bug with how OpenCL is setup more that anything, hopefully
this will help anyone with the same issue.
