Research direction
Start by reproducing the issue in CodeEditSourceEditor 0.3.6 on macOS 15.3.2 using a long file, as described in the reproduction steps. Trace the scrolling and syntax-highlighting behavior from the editor entry points; done means scrolling is smooth and highlighting remains preserved while scrolling. No source file or test is named in the issue.

Description
Description
Scrolling through any file (checked different languages, no custom LSPs installed/enabled) produces slow and visible refreshing of syntax highlighting, which presumably causes scrolling to look choppy and not smooth. See the video below:
To Reproduce
- Open any long-ish file
- Try to scroll through it
Expected Behavior
Syntax highlighting should be preserved during scrolling. The scrolling should be smooth.
