Reproduction

Can be provided if that's not happening for every Nuxt Studio project

A minimal reproduction is not available yet.

The issue happens in Nuxt Studio while editing content in the left editor pane.

It occurs:

• locally
• and on a deployed version running on Cloudflare Workers

Steps to reproduce:

1. Open Nuxt Studio
2. Open any page/content entry in the editor
3. Scroll down so the live preview is not at the top
4. Type anything in the left editor pane
5. The preview jumps back to the top immediately
6. Continue typing and observe repeated flickering and constant scroll resets

I attached a video showing the behavior.

Description

When editing content in Nuxt Studio, typing in the left editor pane causes the preview/editor experience to become unstable.

On every input:

• the page/preview jumps back to the top
• the UI flickers heavily
• it becomes very difficult to edit content further down the page, because the current scroll position is constantly lost

This happens regardless of where I type in the editor and appears to happen consistently.

Expected behavior:

• typing in the editor should preserve the current scroll position
• the preview should update without jumping to the top
• there should be no visible flickering during normal editing

Actual behavior:

• each keystroke appears to trigger a scroll reset to the top
• the interface flickers noticeably
• editing while checking content further down the page is nearly unusable

Additional context

I am not sure whether this is an unintended bug or currently expected behavior in Studio, but from a user perspective it makes the editing experience very difficult.

The issue is reproducible both:

• locally
• and when deployed on Cloudflare Workers

A video is attached to demonstrate the problem visually:

And also the diff is not shown for most changes, no idea why, is this also a bug?

@nicokempe for the diff, I believe this will be fixed soon with the migration to Comark (#355)

As for your other point, I've tried editing some complex components, and I don't have the issue anymore.

Maybe it has already been fixed? Can you still reproduce it @nicokempe?

I haven't updated yet since the last time I tried the deployment to Cloudflare Workers failed and I haven't had the time to troubleshoot the issue but I will try it again soon, thank you very much

Do you know if there is a rough timeline of the Comark migration already or if there is any support needed on the migration?

[TotomInc]

Comark has been released as stable since 2 weeks, it's still recent.

A large part of the migration has already been done in #355, but I cannot speak for @larbish as he's the only one working on it.

I'll release a version with all new features and bug fixes today then I'll finalize the comark migration to have another version dedicated to it. Coming really soon!
