render-stabilizer

Prevents visible screen flicker when resuming or switching sessions.

Without this extension, the TUI can briefly clear and rebuild large parts of the screen while restoring chat content. That redraw path can produce a blank-frame flash, especially in terminals where full-screen clears are visually obvious.

How it works

On first session_start, the extension captures a reference to the active TUI instance.

Before session_before_switch, it resets the TUI render grace period. That nudges the renderer toward gentler line-by-line updates instead of more aggressive screen-clearing redraws during the resume transition.

User-facing behavior

This extension has no commands, tools, or settings.

If it is enabled, session resume should feel steadier and less flashy. If you disable it, resume still works — it just may redraw more harshly on some terminals.

Relationships with other extensions

rewind

rewind and normal session resume both move through session restoration paths. render-stabilizer does not change session data — it only makes those transitions render more smoothly.
