Shaders stopped working completely on my Mac (M1 Pro, macOS latest). Both built-in and custom shaders show nothing on canvas. Layer thumbnail intermittently appears and disappears.
What I've ruled out:
- Browser: Chrome, Safari, Edge, incognito — all fail
- Account: other accounts on same machine also fail; other users on same file see shaders fine
- System: macOS updated, NVRAM reset, Metal shader cache cleared
- WebGPU: confirmed working on third-party demos, Metal compilation logs show 100% SUCCESS
- VPN/network: excluded
This appears to be a Figma-specific WebGPU shader pipeline bug on this hardware/driver combo. Any help or similar experiences?
