I have this setup for Chromium inside Docker

$ cat docker-compose.yaml 
services:
  chromium:
    build:
      dockerfile: Dockerfile.chromium
    environment:
      DISPLAY: $DISPLAY
    network_mode: "host"
    restart: unless-stopped
    tmpfs:
      - /tmp
$ cat Dockerfile.chromium 
FROM debian:bookworm-slim

RUN <<EOF
    apt update
    apt install -y chromium
EOF

CMD ["/usr/bin/chromium", "--disable-dev-shm-usage", "--hide-crash-restore-bubble", "--incognito", "--no-sandbox", "--enable-unsafe-webgpu", "--enable-features=Vulkan", "--hide-scrollbars", "https://play.carimbo.cloud/1.0.0/khromatizo/henrique/0.0.26/480p"]

When I run it on a regular site, it works fine (slow, though).

When I run something that requires HW accel, I get this erro:

chromium-1 | [46:46:0523/145925.458585:ERROR:context_group.cc(146)] ContextResult::kFatalFailure: WebGL1 blocklisted

Even with some flags I was unble to get HW accel.

How to have HW accel?
