[Problem/Bug]: Page is rendered outside of the WebView control #5503
Description
What happened?
One of the users of my application reported that he sometimes gets a display problem with the WebView. The page is rendered outside of the control/dialog. Example screenshot:
The dialog window you see in the background is a WPF window that only contains the WPF WebView2 control. So the page should be rendered in the dialog (and most of the time this works correctly).
The user first noticed this in a few weeks ago (either December 2025 or January 2026).
Importance
Moderate. My app's user experience is affected, but still usable.
