Hey @edvitor13. Thank you for filing an issue! I was also able to reproduce the issue by running one of the @package/driver tests within the develop (SHA 72e6b88) branch, specifically click.cy.js. I am going to document the steps I took below for whoever ultimately works on this bug.

Steps to Reproduce

• after cloning the cypress repository, running yarn to install monorepo dependencies
• in root directory of repository, run yarn workspace @packages/driver cypress:open
• Select E2E Testing
• Start E2E Testing in Chrome (my version installed is v102)
• search and select click.cy.js
• watch test run. eventually auto scrolling stops
• window dimensions did not seem to matter, but for reproduction:
  • Cypress.$(window).width() yielded 1920
  • Cypress.$(window).height() yielded 857

It almost looks like a snapshot is being pinned before the test ends. Not sure if that is related 🤔

Hopefully helpful: I was thinking we might want to not do this scroll listener in run mode? I commented in the other issue but I don't recall if I actually tested that

    scroller.setContainer(this.refs.container as Element, action('user:scroll:detected', () => {
      if (appState && appState.isRunning) {
        appState.temporarilySetAutoScrolling(false)
      }
    }))

Any update on this? I am also encountering the same error. I am running in run mode.

What's the usefulness of enabling the scroll listeners in cli mode? Can user even scroll in headless/cli mode?

@retroace in the comments of this draft PR you can find instructions in the comments from cypress-bot on how to install a pre-release version of Cypress that includes the fix I suggested here.

I actually completely forgot that @AtofStryker had a reproduction in this issue. We probably should have marked these as duplicates of each other.

In any case, since I have trouble reproducing this problem on my computer, feel free to install the appropriate pre-release binary of Cypress and let me know if it works for you. The pre-release turns off the ability for the user to disable autoscroll in run mode, so you will need to either watch back a video, or use cypress run --headed to see your tests running in a way that would be fixed by this draft.

Sometimes it happens to me because Cypress turns off the Auto-scrolling option automatically. So, I need to turn it on again, but once again at some point it is turned back to off.

Cypress: 10.4.1

The code for this is done in cypress-io/cypress#23053, but has yet to be released.
We'll update this issue and reference the changelog when it's released.

Released in 10.8.0.
