During March 2026, Bubby focused on stabilizing GPU rendering and text layout in the ruffle-rs/ruffle repository, addressing reliability issues for large-scale assets. Using Rust and leveraging GPU programming expertise, Bubby implemented a resource management strategy that flushes GPU work during cache entry processing, preventing out-of-memory errors when rendering large bitmap objects. This approach ensured resources were released within a frame, aligning with established backend patterns. Additionally, Bubby refined text measurement logic by treating undefined width as unconstrained in TextFormat.getTextExtent, improving accuracy and robustness. The work demonstrated careful attention to edge cases and enhanced test coverage for rendering paths.
