Cypress 7.1 failing to run intermittently on CircleCI

[tombeckenham]

Current behavior

For some reason every second or third run on Circle is timing out or taking a really long time to run. This started occuring when I upgraded from Cypress 6.8 to 7.1. This is the sort of log we're getting.

circleCiCypress2.txt
There was also a case yesterday which gave a little more information before timing out:

Desired behavior

Cypress to run normally in circle ci without timing out.

Versions

There are some performance issues introduced in recent versions of Cypress, please see those issues for relevant updates. We're working on them.

• [7.0.0] Performance regression from 6.8 (over 3x slower in our test suite) #15853
• Performance regression in CI from 6.6 -> 6.7 (and 6.8/7.0) #15779
• Address performance issues with video recording in Chrome 89+/Electron 12+ #16152
• Cypress hangs in Azure when running headless in 7.0+ #15973
• Test Timing out on Github Actions - Cypress 7.0  #15990

If you are running Cypress in a headless browser, please try reducing the screen size to the default size prior to 7.0 (1280x720) to see if the new issues are related to the increase in screen size. Instructions here.

If that doesn't resolve the issue, I suggest downgrading to the last known version of Cypress that worked well.

We'll be closing this issue as there are no reproducible actions. For now we need to focus on the performance issues where we're given clear reproducible examples.
