I guess it is up to driver, but I have not yet had the opportunity to come in touch with Oreo. Try to experiment changing values in sys.txt, under [rawdisplay] section.
for example
force_renderer="RENDER_MOYA"
driver=GX; GDI, or "engine", or "gles", or...search for more, someone will suggest more solutions. May not seem logical, but in such cases you do not know what will work.
Btw, under
[debug]
put line
show_rawdisplay_info=1 ; handy for seeing what igo chooses as display driver (when you put auto)
