[Problem/Bug]: Webview2 has a blank screen when restored from Minimized state
What happened?
Webview2 has a blank screen when restored from minimized state in some user's machines. Then when we click some where else outside the window the page paints itself and shows the page correctly.
We have the following code for minimising webview:
window.WindowState = WindowState.Minimized;
We have the following code for restoring:
window.WindowState = WindowState.Normal;
Screenshot of blank screen:
Importance
Moderate. My app's user experience is affected, but still usable.

Stable release (WebView2 Runtime)

Framework
WPF
Operating System
Windows 10
OS Version
No response
Repro steps
When the window is minimised and restored on some client machines running Windows 10 Enterprise we can see this happening. Though consistent in these machines, they are not reproduceable in all machines.
Repros in Edge Browser
No, issue does not reproduce in the corresponding Edge version
Regression
No, this never worked
Last working version (if regression)
No response
Update: Introducing a loading when it restores seems to fix this, but there's some issue in webview2 that causes the blank screen in the first place.
I am able to reproduce this issue on Windows 11 24H2 and C++, it's not specific to Windows 10 or WPF.
