Built-in shader effects stopped rendering

Hello! Built-in shader effects, including Duotone and Pattern Refraction, suddenly stopped rendering in Figma. They remain listed in the Effects panel, but their visual output is missing.

I have already restarted Figma, cleared the app cache, tested the browser version, and tried another, more powerful computer.

WebGPU is available, and the WebGPU Report shows successful device and context initialization.

The effects were working normally the previous day.
