Seems like `LinkAnnotation` will cause a performance issue when there are many `LinkAnnotation` in a `Text` , more in thread.

A reproducible example: <https://github.com/Tlaster/LinkAnnotationTest>
I've tested in release mode, when scroll down and make `LinkAnnotation` text visible, the performance is really bad, and it's just 100 `LinkAnnotation`

As for a workaround, custom Annotation with pointerInput modifier to mimic LinkAnnotation behavior is working without any performance issue.

Link annotation creates placeable focusable layouts for the purpose of accessibility and keyboard focus movement. Therefore every instance of LinkAnnotation adds extra cost. I would expect some noticeable difference when there are 100 LinkAnnotations on a single text instance but please file a bug report if you think the performance hit is unreasonable.

I wish it could be better. I encountered this issue in a real-world scenario where a Mastodon post contained many hashtags. Scrolling through the post was very laggy.
