Chromium 66 Dev Tool issues

[ducci1012]

Recently upgraded our project to the latest available Windows build (04/19/2018 - CEF 3.3359.1768.g8e7c5d6 / Chromium 66.0.3359.117). We use use the devtools window frequently for our own debugging. We noticed in the latest update that the "Inspect Element" mode button in the top left is no longer available. Using the Ctrl + Shift + C shortcut still works. We built the CEF examples from scratch and confirmed the button is missing here as well. It appears to still be available in stable Chrome 66.

In our application, we opened the "devtools" on the actual devtools window and noticed a few errors in the console (also attached a screen shot for easier legibility):

Code: Select all

screencast/screencast_module.js:1 Failed to load resource: net::ERR_FAILED
shell.js:22 Empty response arrived for script 'chrome-devtools://devtools/screencast/screencast_module.js'
shell.js:7859 Error: Could not instantiate: Screencast.ScreencastAppProvider at Runtime.Extension._createInstance (shell.js:106)
VM31:1 Uncaught (in promise) TypeError: Cannot read property 'ToolbarButtonProvider' of undefined
    at eval (eval at _createInstance (shell.js:105), <anonymous>:1:26)
    at eval (<anonymous>)
    at Runtime.Extension._createInstance (shell.js:105)


The only reference to this error I've been able to find are vague details here: https://gist.github.com/4D4B/b8b9c3d14fdc88fd3a5663db751aa0ef. I'm unsure if this is something we're able to rectify using the pre-built binaries. Is this an error in the builds, or has something potentially changed that we need to integrate differently with?
