Add Windows-specific wxMSWDisableSettingHighDPIAware() function then can be called before startup (i.e. wxEntry() call) to disable wxWidgets' handling of DPI awareness. This is useful for code embedded in non-wx applications as well as for purely wx application that are not HiDPI-ready (although the latter has the option of forcing dpiAware=false in the manifest). See also https://groups.google.com/d/msg/wx-dev/Z0VpgzCY34U/f1FfPqGDppMJ and #16116. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/branches/WX_3_0_BRANCH@78406 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
