[Problem/Bug]: Intermittently, WebView2 controls are not rendered, and the window behind the dialog with the control is visible through the window.

What happened?

The page loads successfully and the DOM tree is normal, but the rendered screen is not visible.

An issue occurs intermittently, and when the problem occurs, the screen does not appear the same until the management process of msedgewebview2 is restarted.

Setting --ignore-gpu-blocklist --disable-gpu-driver-bug-workarounds did not help solve the problem.

Additionally, when an issue occurs, the web page content is displayed normally in the 3D view of developer tools.

The GPU information file of the PC where the problem occurs is also attached.

Start with the dialog repro where a WebView2 control is created and navigated to the desired page. Reproduce the intermittent invisible-rendering state on Windows 11 using the reported runtime and SDK versions, then compare the visible window with the page shown in developer tools. Done means the rendering failure is reproducible and its cause or a verified fix is documented.
