App shows "out of date" even with latest fork (peff1235) - December 2025

[DaytonCL]

I'm trying to use Figma on Linux (CachyOS, Arch-based) and the app shows "Figma desktop app is out of date" blocking any usage.

I tried building from the most active fork (peff1235/figma-linux) which has recent updates from December 2025 including Electron 35, UI3 support, and Chrome 131 User-Agent spoof.
https://github.com/peff1235/figma-linux
(Unfortunately, the issues section is disabled in that repository.)

Build details:

• Branch: dev
• Commit: a358f30 (Dec 12, 2025)
• Full clean rebuild with npm run build and npm run builder

Console shows multiple unhandled messages:

• setLocales
• initLivegraph
• setThemePreference
• setWorkspaceProperties
• getKeyboardLayout
• setTabColor

I tried:

• Clearing all cache in ~/.config/figma-linux
• Verified Chrome 131 UA spoof is included in the build
• Changed version to 0.11.5 in package.json

Nothing helped. The AUR packages are also outdated.

Is there any working solution for December 2025? Is the original project still maintained or should we rely on forks?

SOLVED!

Changed API version constants in
~/renderer/DesktopAPI/webBinding.ts
(lines 14-15):

// From:
const API_VERSION = 135;
const APP_VERSION = '1.0.0';
// To:
const API_VERSION = 111;
const APP_VERSION = '999.0.0';

Rebuilt with npm run build && npm run builder and the "out of date" error is gone.

The fork was using API_VERSION 135 which Figma rejects. Reverting to 111 (from the original Figma-Linux repo) fixed it.
