Zhiyi Zhang : win32u: Introduce a get_display_depth() helper to retrieve emulated display depth.
Module: wine Branch: master Commit: d81cf4ed555e87e469146829b86bd3bca801efd9 URL: https://gitlab.winehq.org/wine/wine/-/commit/d81cf4ed555e87e469146829b86bd3b... Author: Zhiyi Zhang <zzhang(a)codeweavers.com> Date: Tue Jan 3 22:38:09 2023 +0800 win32u: Introduce a get_display_depth() helper to retrieve emulated display depth. Using EnumDisplaySettings() directly to query display depth has a high overhead when using the XRandR 1.0 display device handler on some NVIDIA setups.
