Webview2 WPF does not render content in x86 mode when launched from Excel - Fixed and Evergreen Runtime

[theboyknowsclass]

Description
No errors thrown, but the window only shows up as blank (there is a foreground message indicating a page is loading however), and right-click and Inspect shows the content is loaded, just not rendered

Version
SDK: 1.0.774.44
Runtime: 89.0.774.63 (also issues with Evergreen)
Framework: WPF, .NET Framework 4.7.2
OS: Windows 10

1. Install both x86 and x64 Evergreen
2. Use sample solution -> https://github.com/theboyknowsclass/WebView2Bug
3. Have both x64 and x86 versions of Excel installed (I was using Microsoft 365 for 64-bit), and 15.0 - 32-bit
4. Debug the app in x64 mode

Expected Result: window should appear with google
Actual Result: window appears with google - yay!

5. Debug the app in x86 mode (you may need to specify the x86 exe in Project Properties -> Debug -> Start External Program)

Expected Result: window should appear with google
Action Result: blank window appears :( - although content is present when right-clicking in the window and selecting Inspect, so it is loading, just not rendering

Thanks for the bug report, I've added this to our backlog to take a look.

[theboyknowsclass]

thanks @champnic - i was testing this on a Win10 VM (in case people are unable to reproduce on a native box)

[champnic]

Does this repro on a local machine at all, or only VM?

[theboyknowsclass]

Sorry, I don't have a equivalent local environment to check it on currently. But a standard wpf project with very similar sample code does render fine in both x86 and x64 on the same setup, so I'm hoping it's more to do with vsto than the vm / remote desktop Sent on the go. Apologies for typos and brevity

this seemed to be something with my configuration as my colleagues could not reproduce, I uninstalled all my office installations , and reinstalled Office 365 (32-Bit) and it now works in 32-bit mode. but there was some instance where it was breaking

@champnic for ref

[champnic]

Thanks for the update. We have heard reports of a similar class of bugs around rendering issues (some around VMs, some around old graphics cards/drivers) so we'll keep looking into this one. But I'm glad it's working for you now.

[theboyknowsclass]

I also had the same issue with the old Webview (again fixed by reinstalling office) Sent on the go. Apologies for typos and brevity
