catbot	cb650f965d	perf(ui): reuse handles vector in WebGPU custom Dispatch (#132 ) UIRenderer::Dispatch built a fresh std::vector<uint32_t> with reserve on every call, paying one malloc+free per dispatch. Custom compute dispatches run per-frame, so make the vector thread_local and clear() it each call: capacity grows to the high-water mark once and is reused thereafter, eliminating the per-frame allocation churn. Behavior is identical. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-18 13:54:09 +00:00

perf(ui): reuse handles vector in WebGPU custom Dispatch (#132 )

UIRenderer::Dispatch built a fresh std::vector<uint32_t> with reserve on
every call, paying one malloc+free per dispatch. Custom compute dispatches
run per-frame, so make the vector thread_local and clear() it each call:
capacity grows to the high-water mark once and is reused thereafter,
eliminating the per-frame allocation churn. Behavior is identical.
