fix: Prevent WebGPU setIndexBuffer crash via geometry disposal quaran…#1120
Merged
Conversation
…tine The "setIndexBuffer" error occurred because geometries were disposed synchronously while WebGPU still had pending draw commands using those GPU buffers. WebGPU typically has 2-3 frames in flight. Added geometry disposal quarantine system that delays geometry and material disposal for 4 frames, ensuring the GPU has finished all pending draw commands before buffers are freed. Changes: - Add geometryQuarantine array and GEOMETRY_QUARANTINE_FRAMES constant - Add queueGeometryForDisposal() to queue resources for delayed cleanup - Add processGeometryQuarantine() called at start of each frame - Update inactive mesh cleanup to use quarantine instead of immediate disposal - Update refreshAllMeshes() to use quarantine - Update dispose() to flush quarantine during full teardown - Apply same pattern to GPUIndirectRenderer https://claude.ai/code/session_01LA6RwJfSB6nsab6v8oAGf9
