[Problem/Bug]: WebView2CompositionControl does not render content when DisableHWAcceleration is set to 1 in WPF

[dipsgin]

What happened?

When the Windows registry key HKEY_CURRENT_USER\Software\Microsoft\Avalon.Graphics\DisableHWAcceleration is set to 1, the WebView2CompositionControl in WPF fails to render any web content. The control remains blank or black despite the WebView2 browser process loading the page successfully.

Is this expected behavior or a bug?
