Hi @jasonria , I am unable to reproduce this locally. Can you try to reproduce this on the correct webview2 sample app https://github.com/MicrosoftEdge/WebView2Samples/tree/main/SampleApps and confirm if the regression is happening here as well.
What is the app framework of saplogon ? Can you share a screenshot with and without regression.

Is this happening consistently with any pdf? What is the framework of saplogon, is it WINUI or WPF or normal win32? Can you try to reproduce the same on the sample application linked above and try navigating to the page which is getting displayed in the saplogon application.
Parallelly can you also validate the same regression on edge 146 beta WV2 runtime as well. A fix was landed wrt print which is now in beta.
