Figma slow on M3 MacBook Air after macOS Tahoe update

It’s been a real nightmare working with Figma files since I updated macOS to Tahoe.

In my file structure, I have a library containing elements used across other files. A few days after updating to Tahoe, the library file appeared fine, with all components intact. However, after publishing a single modification, the other file started resizing numerous elements—mostly icons and images—across multiple screens. Strangely, this included elements I hadn’t even modified.
 

I’ve run several experiments, but the issue persists:

• I switched from the desktop app to the browser version.
• I reverted the file history to a point before the Tahoe update, but as soon as I reopened the working file, it prompted a library update and the elements were misaligned again.
• The only workaround so far is detaching the elements and editing them manually, but this defeats one of Figma’s core advantages: updating repeated elements across screens in one go.
• In the library, the elements appear correctly, but when I copy and paste them into the dependent file, they show up incorrectly.

I’ve already lost four days trying to find a solution.
