Test Report: Sixel Popup Rendering and Cleanup

Date: 2026-02-19 PR: tmux/tmux#4868 Issue: tmux/tmux#4867 Branch: i4867-sixel-display-popup @ 704022a9 Toolkit: tmux Sixel Popup Cleanup Testing Toolkit

Environment

tmux Sixel Popup Cleanup Testing Toolkit

Automated testing infrastructure for verifying sixel image rendering and cleanup in tmux display-popup overlays.

Problem

When a sixel image is displayed inside a tmux popup and the popup closes, pixel artifacts can persist on screen ("ghosting"). This happens because terminal emulators render sixel data in a separate graphics layer that standard

Konsole Programmatic Launch & Screenshot Cheatsheet

Robust recipes for programmatically launching Konsole windows with controlled font, colors, size, and chrome — and capturing non-interactive screenshots. Useful for automated terminal software testing, documentation generation, and CI/CD visual regression.

Also you may want to check this as example for how insights were used for automated and AI Assisted Debugging and Testing of implementing Sixel features for Tmux : tmux Sixel Popup Cleanup Testing Toolkit.

Claude Code CLI: Session Branching & Parallel Conversations - Programmatically via CLI in non-interactive mode!

Experiment: Exploring how to fork a single Claude Code conversation into multiple parallel branches using --session-id, --resume, and --fork-session.

The Idea: Git-like Branching for AI Conversations

Just like git branch lets you explore multiple code paths from a single commit, Claude Code's session flags let you fork a conversation at a decision point and explore multiple directions independently — each branch remembering the

Tmux Popup Notes

Ahhh, this is a good one — this is exactly the kind of terminal ergonomics question that separates casual tmux users from people who live in their terminal.

You’re basically asking:

“How do I open a small ‘box’ over my current running pane and run a command inside it?”
