Bug Report: Timeline Playhead Lag When "Browse" Tab in Essential Graphics Panel is Active

Dear Adobe Premiere Pro Team,

I hope this message finds you well.

I would like to report a bug I have encountered in Adobe Premiere Pro that significantly affects timeline playback performance.

🐞 Issue Summary:
When the Essential Graphics panel is open and set to the "Browse" tab, the timeline playhead lags and stutters during playback. The playback is not smooth, and the delay is noticeable.

However, when I switch away from the "Browse" tab or close the Essential Graphics panel entirely, the playhead behaves smoothly and the timeline playback is restored to normal.

🔍 My Assumption:
I suspect this issue may be related to the way motion graphic templates are loaded or rendered in the "Browse" section. This might be causing performance degradation while the panel is active.

💻 System Info:
I have attached the following for your reference:

✅ Steps to Reproduce:
Launch Adobe Premiere Pro and open any project with a timeline.

Open the Essential Graphics panel and switch to the "Browse" tab.

Begin timeline playback — the playhead becomes noticeably sluggish and choppy.

Hide or close the Essential Graphics panel — playback immediately becomes smooth.
