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

[Tlaster]

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.

Did you file a bug report, in the end?

[Tlaster]

nope, it's just a wish, I'm using the workaround right now and it works ok

[louiscad]

What is the workaround you're referring to?
