🐛 Bug: Playwright screenshot tests pixel diff stuck at >1%, while other NextJS15 DaisyUI projects can 100% fine

Context

I was initially tasked with creating the full Playwright test suite for Socialify (MIT license). After many iterations, @wei and I discovered that for the web app UI (not the generated image URLs), we are only about to achieve >99% and never 100% matching screenshots.

At the time @wei and I thought this is within the natural margin of error.

However, as I'm building my own OSUSWE App at https://github.com/KemingHe/osuswe-app (GPL 3.0 license) using similar tech stack: NextJS 15, Tailwind+DaisyUI, Playwright+GitHub Actions, I noticed that my screenshot tests (with almost identical setup) are able to achieve 100% UI matches very consistently.

This really raises a big question to the source of Socialify's page UI "volatility", for lack of a better term. And I encourage new contributors to use this opportunity to go over the codebase and learn about our architecture as your fist step to contributing.

Edit: grammar

Could there be that somehow the UI is animated, or that the transition doesn't finish properly? Just an idea.
