[PATCH 0/1] MR5772: windowscodecs: Add conversions from PixelFormat32bppBGRA->PixelFormat16bppBGRA5551 and a test.
Bugzilla Issue - https://bugs.winehq.org/show_bug.cgi?id=56755 This addresses an issue in EverQuest with some older models having white textures since a game patch earlier in the year. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5772

Thank you for the heads up - I just updated my profile To clarify, you need to either have your GitLab name match the name you use for patches, or manually approve all patches you send. The system we have is that approval is implicit for your own patches, but requires explicit action for someone else's.
