- **Bear Version** : Version 2.6 (13715)
- **OS Version** : macOS 26 Tahoe
- **What were you doing** : Navigating around the app (scrolling, opening/closing the tags list and notes list) with a note open that contains MathJax.
- **What feature did you use** : Navigation, MathJax
- **What happened** : When I have a note open that has several lines of MathJax, e.g. for my MS in Data Science homework, scrolling seems to be stuck at a low refresh rate. Opening/closing the tags list and notes list is extremely laggy and choppy. I tested this with a new note with only a few lines of MathJax and it was smooth. But the notes with \>10 equations make the program stutter.
- **What did you expect to happen** : Buttery smooth navigation. The butterier the better.

I can confirm that the latest version on MacOS (2.6.4) fixes this issue!

I would like to chime in to say that I still have the jittery scrolling problem in Bear 2.6.5 on Tahoe 26.1. I can provide a sample file if needed.

The Tahoe 26.2 update seems to have fixed the issue.
