Expected Behavior

Mactype should be able to apply its font rendering settings, in this case greyscale anti-aliasing, to obs-studio's UI rendering.

Current Behavior

Starting with version 31.1beta1 and up, Mactype has no effect on obs-studio's UI text rendering, but MacType64.Core.dll and MacType64.dll appear to be loaded according to System Informer. Versions 31.0.4 and below are not affected.
Tested versions:
Affected: 31.1.0, 31.1beta1, 31.1beta2, commit 28960a4
Not affected: 31.0.4, 30.2.3, 27.2.3

Steps to Reproduce

1. Install Mactype: https://github.com/snowie2000/mactype/releases/tag/v1.2025.6.9
2. Open C:\Program Files\Mactype\ini\Default.ini and on line 15 change AntiAliasMode=4 to AntiAliasMode=1 (greyscale antialiasing).
3. Run Mactype for the first time, choose Service mode or Tray mode, choose the Default profile, apply.
4. Run MacTray if Tray mode was selected. Effects of Mactype should be visible immediately, e.g. Explorer should show greyscale antialiasing of folder contents instead of ClearType's RGB. ClearType should remain enabled. See image for comparison:

6. Run obs-studio.

Anything else we should know?

I looked at https://github.com/obsproject/obs-studio/compare/31.0.4...31.1.0-beta1 , and 28960a4 was one of the oldest commits with available binaries.

Reproduce the issue on Windows 10 with OBS Studio 31.1beta1 or newer and MacType using the supplied settings. Compare the 31.0.4...31.1.0-beta1 changes, especially around UI rendering, and confirm the fix when MacType's greyscale font rendering applies to OBS Studio text without changing the reported ClearType behavior.
