Indent guides make scrolling less performant

[hihayk]

The plugin makes the scrolling in brackets less smooth.

@hihayk, that is correct. Any extension that creates a large number of stylized spans via CodeMirror overlays makes scrolling less smooth. As another example, take a look at the Show Whitespace extension. It also uses a lot of CodeMirror overlay stylization as well and has a similar problem.

Unfortunately, unless there is another way to implement indent guides that doesn't use CodeMirror overlays that I don't know about, there isn't a lot I can do about it. Certainly open to any ideas or suggestions though.

Thanks Lance, I'm not a developer so I can't suggest anything.
Anyway I love the extension, and made the lines color brighter.

Changing this issue to a code challenge.

Is there a way to make CodeMirror mode overlays more performant?

Are there any other ways to implement indent guides without using CodeMirror mode overlays?
