[PATCH resend 2/4] winemac.drv: Store monitor information in the wineserver for EnumDisplayMonitors(). - wine-devel

25 Feb 2021

Fix a regression that Office 2016/365 has a 640x480 main window.
Office 2016/365 hooks NtOpenKeyEx() and prevents access to SetupAPI device properties.
After querying monitor information from SetupAPI failed, EnumDisplayMonitors() reports
a fallback monitor of size 640x480.
As to why store the monitor information in the wineserver, it seems that EnumDisplayMonitors()
reports monitors connected to current user logon session. For instance, EnumDisplayMonitors()
always report one monitor when called by services.
