Additional Information

MetaMask 4.3 did not have this issue.

From another channel, the issue is reportedly caused by a #8326. The MetaMask team is going to add a feature-test to ensure this API exists before making a call. That being said, we should explore implementation sooner rather than later.

However, the user has ran into the above issue on MM 4.3.0 and not 4.6.1.

I am experiencing it myself. Even reinstalled Brave but nothing happened. Version 4.3.0 but, can't find how to upgrade the version. It happened that on Web3 websited did loaded the address as locked. Hopefully it can be fixed. Is a bummer.

Just letting know that this happened to me.

The issue here is with the chrome.i18n.getAcceptLanguages method. If this method is called without evaluating chrome.runtime.lastError in the callback, an exception will be thrown. The exception causes the flickering.

We're working on a solution :)
