Those are kinda hard to investigate, and not that interesting TBH, unless they block progress. In the past I've had moderate success with limiting maximum sizes for things like command buffer Buckets (I think that should be applying to passthrough) or buffer objects (because of shadow memory), see https://cs.chromium.org/chromium/src/gpu/command_buffer/tests/fuzzer_main.cc?q=fuzzer_main.cc&sq=package:chromium&dr&l=397 Not sure if something similar is applicable here.

This is likely due to the scratch memory allocated to zero-initialize buffers.
