Cypress 14 performance degradation in certain circumstances on linux, in electron, in headless mode #30980
Description
Current behavior
There is a degradation in performance on linux, in electron in headless mode. This can be seen with this project. The performance seen is:
| Spec | Cypress 13.x | Cypress 14.0 |
|---|---|---|
| alert.cy.js | 00:03 | 00:05 |
| analysis.cy.js | 00:23 | 00:53 |

| All specs passed! | 02:59 | 08:57 |
After some digging, it appears that this happens specifically when we upgrade to 28.0.0 in Electron (we upgraded to 33 as a part of 14 but specifically 28.0.0 seems problematic). Looking at the test replay of what is happening in these tests, it appears that at least one of the main culprits is a v-menu is taking 3 seconds to dismiss where it previously took .1 seconds.
Desired behavior
There should not be a performance degradation.
