256K ULPs, which is crazy to me. See https://gitlab.winehq.org/wine/wine/-/merge_requests/3172#note_43940

Assuming there isn't some other explanation for the huge discrepancy, I think we should simply consider QXL not a suitable test platform. In this particular case, though, testing filtered sampling is not the point, while testing shader translation is, and the updated test does a better job of that as well IMO.
