Description
What happened?
In our Win32 app using WebView2 visual hosting (DirectComposition), text inside the WebView becomes blurry/dim when hovering the app icon on the Windows taskbar (taskbar thumbnail / live preview appears).
When the WebView/window is activated again, text clarity returns to normal immediately.
This does not happen in our windowed hosting mode.
Importance
Important. My app's user experience is significantly compromised.
