Option to disable dynamic timeline thumbnail refresh in Premiere Pro 2026

Hello,

I would like to report a workflow issue introduced in Premiere Pro 2026 regarding timeline thumbnails.

In Premiere Pro 2025, when stretching or trimming a clip on the timeline (especially long-form footage), the video thumbnails remained visually stable. Even when thumbnail display was enabled across the clip, they did not dynamically refresh or “scroll” during trimming.

In Premiere Pro 2026, when I stretch a clip on the timeline to quickly locate a moment within a long recording, the thumbnails now dynamically refresh and scroll in real time. This creates constant visual movement inside the timeline itself.

For long-form editing (40+ minute timelines), this behavior is:

• Very visually distracting
• Disorienting while trimming
• Uncomfortable for precision editing
• Slightly heavier on performance during rapid scrubbing

I only want to see image updates in the Program Monitor — not continuously inside the timeline thumbnails.

Is there currently a way to disable dynamic thumbnail refresh and return to the 2025 static behavior?

If not, I would strongly request the addition of a preference toggle to:

• Disable dynamic timeline thumbnail refresh
• Or restore the previous static thumbnail behavior as an option

Without this option, it becomes difficult for me to continue working comfortably in 2026.

Thank you for considering this request.
