Comment 26 for bug 231953

So yes, this is likely caused by https://gerrit.libreoffice.org/#/c/238/. We could:
1/ simply revert that and have LibreOffice behave as needed for accessibility
2/ keep that and only behave as needed for accessibility when "automatically detect high contract mode of operating system" is checked in the options.

For 2/, here is a an example of how to read that value: http://opengrok.libreoffice.org/xref/core/vcl/source/window/window.cxx#636

Im not convinced that that is the right way to go: We are mixing two usecases here: a/ accessibility and b/ people using a dark desktop theme without a need for accessibility.

Ultimately, IMHO what we really need is a dark theme no-accessibility theme, so that we can keep these too apart.
