App needs to be on PerMonitorV2 DPI awareness to look properly

[michael-hawker]

After following step 3 of the Getting Started, I see the WebView2 offset:

WinVersion: 17763.437
NuGet: 0.8.149

Resolution/DPI: 2256x1504 @ 150% (Surface Laptop 2)

If I set my DPI to 100% it seems to work fine.

Thanks. I've opened a bug to track this. Perhaps we're missing some DPI awareness calls from the sample and documentation.

Hi, we're currently working on our documentation. It does indeed have to do with DPI awareness. To fix this, you need to be per monitor DPI aware. You can either set it in the manifest or add a call before you create the HWND:

SetProcessDpiAwarenessContext(DPI_AWARENESS_CONTEXT_PER_MONITOR_AWARE_V2);

Have a PR out to update the getting-started walkthrough - MicrosoftDocs/edge-developer@ec53ad2. Will leave this issue open as long as the behavior remains the same.

Update - doc PR is merged.
