I think the non/integer pixel ratio must be the deal. I did.a quick test and on
all three of my displays, the pixel ratio is always 2.0 or 1.0 regardless of
which screen and how I set up the scaling. Maybe there is something with MacOS
where not integer pixel ratios are handled under the hood and it fakes exactly
2.0 or 1.0?
