Yes, but according to the docs, in compatibility mode, "Any
vector-based drawing performed by an app is scaled for high
resolution"

The Mac LibreOffice screenshots in bug reports I have seen have
doubled vector drawing. I think there is something wrong with your
build. In any case, if you feel something should be done for the Mac,
the simplest thing is to add two #ifdefs to force the DPIScaleFactor
to 1 for the Mac:

https://gerrit.libreoffice.org/#/c/8516/1/vcl/source/window/window.cxx,cm

That would turn off all bitmap doubling in a very localized place.
What do you think about that?
