Description

When running opencode inside a VM or container, the opening screen is blank for approximately 10 seconds before the UI renders and becomes responsive. After this initial delay, the application responds promptly.

When running locally (not in a VM/container), the application starts instantly with no blank screen delay.

This behavior has been observed in multiple virtualization/container setups:

Plugins

N/A

OpenCode version

Latest

Steps to reproduce

  1. Run opencode inside a virtual machine or Docker container
  2. Observe blank screen for ~10 seconds on startup
  3. After delay, app becomes responsive and works normally

For comparison:

  1. Run opencode locally (not in a VM/container)
  2. Observe instant startup with no delay

  • #7200: Blank in WSL2 Ubuntu Terminal/Desktop (blank screen in virtualized environment)
  • #11092: OpenCode does not show UI in terminal or web (UI not appearing during initialization)
  • #4755: opencode Terminal UI shows empty screen (empty/blank screen on Ubuntu)
  • #8074: Opencode not loading (stuck on "Initializing..." during startup)
  • #820: Slow chat startup (startup delay caused by blocking operations during initialization)

For example, using the following dockerfile:

docker build -t opencode-test .
docker run -it --rm opencode-test

FROM ubuntu:24.04

# Install dependencies
RUN apt-get update && apt-get install -y curl && rm -rf /var/lib/apt/lists/*

# Install opencode using the official install script
RUN curl -fsSL https://opencode.ai/install | bash

# Add opencode to PATH
ENV PATH="/root/.opencode/bin:$PATH"

# Set working directory
WORKDIR /workspace

# Run opencode on container start
CMD ["opencode"]

If I set the following environment variable, opencode starts instantly:

OPENCODE_DISABLE_DEFAULT_PLUGINS=1

It looks like the plugins that this disabled are just:
