Module: wine Branch: master Commit: 8a8808e98b1f902ba8cca7559814a25fbfd0d8b6 URL: https://source.winehq.org/git/wine.git/?a=commit;h=8a8808e98b1f902ba8cca7559... Author: Tim Clem <tclem(a)codeweavers.com> Date: Tue Mar 22 11:06:00 2022 -0700 winemac.drv: Add a flag to filter unsupported modes in copy_display_modes. Prefer supported display modes over similar unsupported ones. Centralizes the logic from the ChangeDisplaySettingsEx and EnumDisplaySettingsEx implementations.
