Webview poor performance on Win32

Solar2D Win32 Desktop

Hello, i’m noticing poor performance of the webview under windows. All is fine on Android (have not tested on iOS).
I am displaying a virtual reality tour, using multitouch and drag… performance is pretty bad, screen is laggy and loading times are long. Same website on edge or chrome displays fine. Like i said, same app under Android works perfectly. Maybe an optimizarion issue considering feature was only recently added?

I too am experiancing very slow performance on win32.

Thanks.

Can you post your code that creates the webView here?

Thanks

Voilà:

webView = native.newWebView( 0,0,2048,1456 )

webView.anchorX = 0

webView.anchorY = 0

webView:request( “https://my.matterport.com/show/?m=1DhQMM9QNjX&mls=1” )

sceneGroup:insert(webView)

webView:addEventListener( “urlRequest”, webTouchTimerReset.webListener)

Cheers,

Alex.

Before I test this on Windows, the URL above generated 34.9 megabytes of data over 500 HTTP requests and the onload event (indicating that the page was done loading) happened 2 min and 28 seconds and I’m on a fiber connected line.

The website did a great job of masquerading the amount of data and requests by getting the necessary data to display the above the scroll visuals rather quickly. I was pretty impressed at how fast it seemed to load.  

Now my windows tests didn’t show any performance problems. The WebView in both the simulator and in a built Desktop app loaded just about as fast as the URL did in Firefox and Internet Explorer, Edge and Chrome They all hit about the same pause points in the loading circle.

Now trying to drag the view around was noticeably slower in Firefox and the webView than it was Chrome and Edge. But they all lagged.

I tried resizing the webView and content area of my test app down to something smaller.  You’re webView is quite large. 

I no doubt that there is some tuning that the webView could benefit from, but it took considerable work to get any webView in for Windows. Knowing our current priorities and engineering tasks, we won’t be getting to this in the next few months. But for us to have any chance, we are going to need a bug report.

Please put together a complete project:  main.lua, build.settings, config.lua and put it in a .zip file and email it to support@coronalabs.com and I’ll see that it gets into our bug tracking system. Please provide a good description of the problem.

Thanks
