Mac driver version of a8b4cf7f2d3d1fbd79308a106a84e753cdac69e8. Combined with the previous patch that reordered synthesized modes, the Mac driver implementation of EnumDisplayModesEx now returns modes in the same order as the X11 driver.

Hi, While running your changed tests, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check? Full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=110874 Your paranoid android. === debian11 (build log) === Task: Patch failed to apply === debian11 (build log) === Task: Patch failed to apply
Hi Dean-- The display mode enumeration patches are unrelated to the Metal issues, as far as I know. These patches help certain applications that expect lower resolutions to be first in the results from EnumDisplaySettingsEx, or ones that only enumerate a fixed number of resolutions before giving up (e.g. Quake). --Tim March 21, 2022 3:08 PM, "Dean Greer" <gcenx83(a)gmail.com> wrote:
