According to Boris Cherny on X (Twitter), Anthropic has introduced a NO_FLICKER mode for Claude Code in the terminal that uses an experimental renderer aimed at eliminating screen redraw flicker and improving readability for AI-assisted coding workflows (source: @bcherny tweet, Apr 1, 2026). As reported by Cherny, most internal users prefer the new renderer over the previous implementation, indicating measurable UX gains for code generation, inline edits, and streaming completions in terminal environments (source: @bcherny). According to the post, the renderer is early and carries tradeoffs, suggesting businesses should pilot it in developer toolchains where stable streaming output and low-latency diffs drive productivity gains for AI pair programming and code review (source: @bcherny).
