Edge Webview2-based application window displays an exception at the bottom

Description
Edge Webview2-based application window displays an exception at the bottom

When a Webview2-based application is opened, a small transparent area appears at the bottom of the window, sometimes flashing black and white. The window appears normal when it loses focus.

(The app's window content does not overflow, and there is no scroll bar set, dragging and resizing the window will disappear briefly and then reappear)

Previous versions of Edge Webview2 did not see this issue and started to appear after 107.

Version
Runtime: 107.0.1418.35
OS: Windows 11 Pro Dev Channel (Build 25236.1010)

Repro Steps

1. Open an app based on Edge Webview2, and focus on its window.
2. See the bottom of this app, you may notice a thick area

Can you share a screenshot of the issue? What framework are you using (Win32, WPF, WinForms, WinUI)?

I tried using our Win32 WebView2APISample app, but I don't think I see the transparent area you are referring to. Can you repro the issue using one of the WebView2 Sample apps that matches your framework? Or if not, can you provide a repro app?
