[desktop-feedback] Docker Desktop 4.93.0 Dashboard fails: GPU child crashes normally; renderer crashes with --disable-gpu-sandbox

## Observed symptom Docker Desktop 4.93.0 Dashboard fails: GPU child crashes normally; renderer crashes with --disable-gpu-sandbox This appears related to #551, but the environment and failure mode differ. In my case, Docker Desktop 4.93.0 still fails on Windows 11 26H2 with an RTX 3090 Ti, and a one-shot `--disable-gpu-sandbox` test suppresses the repeated GPU-child failure but exposes a renderer `STATUS_BREAKPOINT` instead. Docker Desktop 4.93.0 Dashboard does not load on Windows 11 Pro 26H2 (build 26300.9550), although the backend and Docker Engine reach the running state and read-only `docker version` / `docker info` succeed. ## Environment GitHub docker/desktop-feedback #712 ## Trigger / context Public GitHub report in docker/desktop-feedback (FRESH_7D). ## Source evidence - https://github.com/docker/desktop-feedback/issues/712 (2026-09-30T03:21:12Z) — evidence_class: PRIMARY_ISSUE_REPORT — #712 ## Freshness - classification: FRESH_7D - retrieved_at: 2026-10-02T10:42:44.319212Z - scout_id: Cc33b90e298 ## Scout notes This Problem was published by the KFA Fresh Friction Scout from public sources.
