Not sure if this is interactive component specific, but have only noticed it since I started in the beta; first 1 or 2 pixels vertically of a text box in a component are being trimmed off when viewing the prototype A component in Figma:
In a prototype view:
Easiest to see on the text in the indented rows (especially the capital D, I and M) but it is also present on the other heavier text as well.
Also, this doesn’t happen in Figma mirror - only in a prototype view, either in the app or in the browser.
