Esme contributed to ValveSoftware/Proton by engineering compatibility and stability improvements across multiple releases. She upgraded core dependencies like Wine Mono and Xalia, managed build and configuration systems, and enhanced game compatibility for Unity3D and Rockstar Games Launcher titles. Using Makefile, Python, and Gudl, Esme implemented targeted fixes such as SysLink integration and input handling adjustments, while also refining environment variable management and feature flag controls. Her work addressed both broad compatibility needs and specific edge cases, such as disabling Xalia for Wuthering Waves, demonstrating a methodical approach to risk reduction, maintainability, and user experience in complex cross-platform environments.
July 2025: Implemented a targeted bug fix in ValveSoftware/Proton to disable Xalia for Wuthering Waves (App ID 3513350). This prevents the gamepad UI for keyboard/mouse from activating, addressing CW-Bug-Id #25642. Delivered via commit 54c06cf938b9d87464bab08391288b40a9c42c4c. This change improves input reliability and UX for keyboard/mouse players, reduces support overhead for this title, and demonstrates careful, minimal-risk feature flag control.
