Preventing browser flickering when using 'loadURL' to switch between URLs in Electron

Within my electron app, I am utilizing a singular window. As users navigate through the various "forms" within the application, I make use of the mainWindow.loadURL('file://...') function. Unfortunately, this approach leads to a flashing effect where the browser window clears its content before loading the new HTML file. This results in a non-native user experience which is far from ideal. Additionally, I have already explored using the "backgroundColor" option when creating the window like so:

mainWindow = new BrowserWindow({
        width: 1000,
        height: 600,
        backgroundColor: '#2e2c29'});

However, this solution does not fully address the issue (the background of the app still flashes white for a second or more during URL switches).

Is there a workaround to prevent this unwanted flashing effect?

Expanding on previous suggestions, here is a simple illustration:

const { app, BrowserWindow} = require('electron');

function openNewWindow(){
    let window = new BrowserWindow({
        width: 1000,
        height: 600,
        backgroundColor: '#2e2c29'
        show: false
    });

    window.loadURL(`file://${__dirname}/views/index.html`);

    window.once('ready-to-show', function (){
        window.show();
    });

    window.on('closed', function() {
        window = null;
    });
}

app.on('ready', function(){
    openNewWindow();
});

This method is commonly used for creating new windows, but there may be alternative approaches such as using timeouts to ensure the window is ready for display.

When exploring the electron-api-demos on GitHub, I discovered an intriguing example of loading different "forms". The demo showcases all forms being loaded in the repository, but only one form is made visible at a time based on user interaction.

On the other hand, the Pluralsight course "electron playbook" takes a different approach by creating a "view engine" using Handlebars or Jade combined with jQuery. This method involves treating each "form" as a Handlebars template that can be rendered and then attached to a div in index.html. This allows for multiple forms within a single window electron app.

Lately, I've encountered a persistent issue that has been troubling me for quite some time. However, the recent release of electron 2.0.0 has provided a solution by allowing users to set the affinity to confine all page loads within specific BrowserWindows. This optimization has significantly improved CPU usage as it consolidates the loading process into one.
