Issue Details

• Electron Version: v11.0.0-beta.19
• Operating System: macOS 11.0.1
• Last Known Working Electron version:

I've created a minimal repro for you. Download the repo:

git clone git@github.com:ccorcos/electron-browser-view-drag.git
cd electron-browser-view-drag
git checkout side-browser-view
npm install
npm start

There's a the default index.html inside the window's webview, and what I did is add a BrowserView to render search.html and you'll notice that button is not clickable. However, you can drag the whole window when you click in there...

Expected Behavior

Should be able to click the button inside a BrowserView.

It seems like there has been a regression in Electron 11. The BrowserView seems to always be a draggable region regardless of -webkit-app-region. Electron 10 works fine. cc @codebytere

@poiru i'm not sure what you mean and did not see drag behavior in frameless windows where none was enabled 🤔 Do you have a specific repro in mind?
