Enable WebGPU on Flatpak Chrome (Linux)

WebGPU isn't enabled by default on Linux Chrome. Here's how to enable it for Flatpak Chrome.

Quick Setup

Create the config file at ~/.var/app/com.google.Chrome/config/chrome-flags.conf with these contents:

--enable-unsafe-webgpu
--ozone-platform=x11
--use-angle=vulkan
--enable-features=Vulkan,VulkanFromANGLE

Then restart Chrome.

What the flags do

• --enable-unsafe-webgpu - Enables WebGPU API
• --ozone-platform=x11 - Required because Vulkan ANGLE isn't compatible with Wayland
• --use-angle=vulkan - Use Vulkan backend for ANGLE
• --enable-features=Vulkan,VulkanFromANGLE - Enable Vulkan features

Notes

• This runs Chrome under XWayland instead of native Wayland
• Make sure your graphics drivers are up to date
• Intel Gen12+ GPUs have WebGPU enabled by default in Chrome 144+

Test it
