#### Why won't `hardened-chromium` start on Nvidia?
On some Nvidia machines, `hardened-chromium` defaults to the X11 backend. Since secureblue disables Xwayland by default, this means that you will need to run `ujust toggle-xwayland` and reboot, for `hardened-chromium` to work.
### Why don't some websites that require JIT/WebAssembly work in hardened-chromium even with the V8 Optimizer toggle enabled?
This is an [upstream bug](https://issues.chromium.org/issues/373893056) that prevents V8 optimization settings from being applied to iframes embedded within a parent website. As a result, WebAssembly may not function on services that use a separate URL for their content delivery network or other included domains, such as VSCode Web (https://github.dev). To make VSCode Web work properly, you need to manually allow V8 optimizations for the CDN by adding `https://[*.]vscode-cdn.net` to your list of trusted websites.
