Describe the bug
After updating Visual Studio to the latest Insider/Preview build [11822.327], the One Dark Pro theme color mapping appears to be broken. It seems like Microsoft introduced some structural changes to the VS internal theme engine, causing colors, syntax highlighting, and UI elements to render incorrectly compared to previous versions.
To Reproduce
- Update Visual Studio to build
11822.327 (Insider/Preview).
- Activate the One Dark Pro theme.
- Observe the editor syntax highlighting and UI component colors (they are mismatched or reverted to default fallback tokens).
Expected behavior
The theme should properly map the One Dark Pro color palette across the text editor, activity bar, and general VS shell UI elements as it did in prior builds.
Environment
- Visual Studio Version: 2022 / 2026 Insider (Build 11822.327)
- Extension Version: Latest
- OS: Windows 11 / 10
