# Objective - wgpu 0.20 made workgroup vars stop being zero-init by default. this broke some applications (cough foresight cough) and now we workaround it. wgpu exposes a compilation option that zero initializes workgroup memory by default, but bevy does not expose it. ## Solution - expose the compilation option wgpu gives us ## Testing - ran examples: 3d_scene, compute_shader_game_of_life, gpu_readback, lines, specialized_mesh_pipeline. they all work - confirmed fix for our own problems --- </details> ## Migration Guide - add `zero_initialize_workgroup_memory: false,` to `ComputePipelineDescriptor` or `RenderPipelineDescriptor` structs to preserve 0.14 functionality, add `zero_initialize_workgroup_memory: true,` to restore bevy 0.13 functionality. |
