Bug: Large edits cause syntax highlighting rainbows

[airjp73]

I noticed a visual bug when deleting many lines at once. Something not shown in the gif here is, sometimes the syntax highlighting doesn't fully correct itself until making further edits.

Operating System: Windows
File in the Gif: On Github here
Command in the Gif: :g/*/d

Thanks for the issue, @airjp73 !

Indeed, syntax highlighting is one of our biggest performance bottlenecks at the moment. We're tracking moving to a native syntax highlighting here in #161 - most likely tree-sitter.

If I'm remembering correctly, this was before the native tree-sitter and native textmate.

Is this still an issue now, or can this be closed out?

I just downloaded the latest version on the website and it looks like the state of this issue has definitely improved. There's still some wonkiness but not the crazy rainbows there were when I reported the issue originally.

Thanks for the update @airjp73 !

We just merged #922 yesterday, which should improve this even further reduce that 'waterfall' effect you were seeing in the latest gif).

The next step for us is to switch to using more tree-sitter syntax highlighter!

This should be fixed now by #771 (use native textmate highlighting) and #922 (asyncify the syntax highlighting) - so I'll close this out. Feel free to log a new issue if you are still seeing issues.

Thank you for reporting and for the update, @airjp73 !
