Windows demo gpu bug

[lihuayu315]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I'm currently using the Windows platform of this project with the built - in webview function. However, I've found that even when the web page is static, the program still consumes a lot of GPU resources. At present, I'm in a multi - screen setup. It's consuming 3D resources on a 4K screen and copy resources on a 2K screen. I want to know what's causing this problem

Expected Behavior

I think the GPU resources shouldn't be consumed when the web page is static.

I'm having the same issue of an unexpectedly high GPU usage.
I noticed that also another flutter library webview-windows has a similar issue jnschulze/flutter-webview-windows#308

As Microsoft WebView2 Windows API doesn't currently have an offscreen rendering API, it uses the same implementation of webview_windows plugin, otherwise, we won't have a way to make it work on Flutter.

When WebView2 will have an offscreen rendering API, this issue will be resolved.
Here is the issue about it on the official WebView2 repo: MicrosoftEdge/WebView2Feedback#20, MicrosoftEdge/WebView2Feedback#547

Unfortunately, 4 years have passed but this feature has not yet been implemented by the Microsoft WebView2 team.

Also, there are some other issues with the current implementation: MicrosoftEdge/WebView2Feedback#4944
