The Bugbug bot thinks this bug should belong to the 'Core::CSS Parsing and Computation' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Hi sadpala,
I looked over the Chromium bug which has this testcase: https://play.tailwindcss.com/CDTzBIp1N2, but I can't reproduce the flickering on the latest Firefox versions (Release 93.0, Beta 94.0b10, Nightly 95.0a1) on Windows 10, Linux nor MacOS 10.15.
Can you reproduce it on your side?

I am assuming this is a WebRender issue (or at least something related).

It works now.
