VSCode has a strange white underline.

Type: Bug

There is no regularity, and the folding function is also unusable when the white line appears

Also, please use the Start Extension Bisect command to investigate whether the issue is being caused by one of your extensions.

Thanks for reporting this issue! Unfortunately, it's hard for us to understand what issue you're seeing. Please help us out by providing a screen recording showing exactly what isn't working as expected. While we can work with most standard formats, .gif files are preferred as they are displayed inline on GitHub. You may find https://gifcap.dev helpful as a browser-based gif recording tool.

If the issue depends on keyboard input, you can help us by enabling screencast mode for the recording (Developer: Toggle Screencast Mode in the command palette). Lastly, please attach this file via the GitHub web interface as emailed responses will strip files out from the issue.

Happy coding!

sorry. this is what I captured today. maybe it's an issue with the extension.

[gjsjohnmurray]

Did you try the Start Extension Bisect command?

When the window reloads, this issue also disappears, so it is not consistently reproducible. However, it seems to be caused by vue.volar.
