Terminal UI Issue – Continuous Blinking & Scroll Reset

Description

When the number of tasks reaches the visible size of the terminal window, the terminal begins blinking continuously. During this process, if the user scrolls, the scroll position is automatically reset to the top, making it difficult to review previous logs or output.

This behavior negatively impacts usability when monitoring long-running tasks or reviewing earlier terminal output.

Observed Behavior

• When tasks fill the terminal viewport:

  • The terminal refreshes/blinks continuously.

• If the user scrolls up while the process is running:

  • The scroll position jumps back to the top automatically.

• This prevents users from reading previous logs while tasks are executing.

Expected Behavior

• The terminal should not blink or redraw excessively.
• If the user scrolls manually, the scroll position should remain fixed until the user returns to the bottom.
• Terminal updates should append output without forcing scroll resets.

Suggested Fix

Possible improvements include:

1. Prevent full terminal redraws

   • Update only changed lines instead of re-rendering the entire terminal.

2. Preserve scroll state

   • Detect if the user has scrolled away from the bottom and pause auto-scrolling.

3. Throttle UI updates

   • Reduce refresh frequency to avoid blinking.

4. Conditional auto-scroll

   • Only auto-scroll when the user is already at the bottom of the terminal.

Priority

⚠️ High Priority UI Issue

This should be addressed as soon as possible because it affects usability when monitoring active tasks.

Additional Feedback

Other than this issue, the system works very well overall.
I will continue testing and help identify more UI bugs if they appear.
