Crate rdesktop_cef 

rdesktop-cef: Chrome/Chromium backend for cross-platform pixel-perfect rendering.

This renderer controls a Chrome/Chromium instance via the Chrome DevTools Protocol (CDP). It provides identical rendering across Windows, macOS, and Linux since it uses the same Chromium engine everywhere.

Architecture

• Chrome is launched as a headless subprocess
• Communication happens via CDP (WebSocket)
• Pages are created and controlled via the CDP API
• The IPC bridge is injected via page.evaluate()

Requirements

• Google Chrome, Microsoft Edge, or Chromium must be installed
• The renderer auto-detects the Chrome executable on the system

Trade-offs vs WebView

Aspect	WebView	Chrome (CDP)
Bundle size	~5MB	~150MB (Chrome required)
Rendering	Platform-specific	Identical everywhere
Native window	Yes (tao)	Headless (screenshot-based)
Performance	Native	Slight overhead (CDP + screenshot)
