Worked on stabilizing the Shader Graph Blackboard UI within the Unity-Technologies/Graphics repository, focusing on improving editor performance for complex shader graphs. Addressed a persistent issue where hierarchy geometry changed events in the scroll view content container caused unnecessary update cascades, leading to UI lag and rendering glitches. By disabling these events, the solution reduced performance bottlenecks and preserved editor responsiveness, directly benefiting artists and engineers iterating on shaders. The work was implemented in C# and leveraged expertise in Shader Graph and Unity Editor Development. Clear documentation and traceability were maintained through descriptive commit messages linked to the relevant issue.
