The one I bought is labelled an R350, which supposedly is amdgpu
but it responds as an R250 and doesn't use amdgpu and doesn't work
as well as the HD5450 so I think I'll be returning it.

I anyone has a recommendation for a more modern amdgpu board that
does work well with -current and freecad, qcad or kicad, I'd like
to hear about it as none of the above work well with either of my
gpus.

I tried that with the HD5450 and mpv gets long horizontal stripes
all over the window at the beginning, but does clear up later.  I
don't really use mpv much. It's just something that has trouble
since NetBSD 10+ that was something to mention. It's mainly freecad
and kicad that I'd like to have working without all of the window
trash.

Thanks!!
