@roboterm , can you please share repro in WebView2 samples? Can you please also share the webview2 runtime version where you are facing the issue and the version where it was working fine?

[roboterm]

impacted version: 144.0.3719.82
working version: 143.0.3650.139

[ambikakunnath]

@roboterm , can you share detailed repro steps that can help us repro the bug?

[roboterm]

@ambikakunnath this happens in SAP IS-H modul which uses the webview as browser control.
it is observable when using transactions like NV2000 where the patient header is missing.
Hardly to reproduce if no SAP is available.

@roboterm can you please help us with a repro in Sample app - https://github.com/MicrosoftEdge/WebView2Samples/tree/main/SampleApps/WebView2APISample
Also, can you share the traces with the issue for us to have a look?

I can confirm that this is problem of version 144. It's documented by SAP under note "3704912 - Latest Webview2 Version 144.xxx causes problems with SAP GUI HTML control when using edge as browser control in SAP GUI for Windows".

Good sample is SAP Business Workplace (task inbox in S/4HANA or ECC). If you open some workflow request (ex. invoice approval) with version 1.143 you will see decision buttons and links to attachments. With version 144 you will see only blank window.

In the meantime, SAP has provided a workaround (see SAP Note 3704912).
While this workaround does work, it unfortunately introduces additional issues in other transactions related to the PDF print preview and display.

The reason we need a minimal repro or a sample repro is so that we can isolate the issue from Webview2 and the App.
Traces can also help isolate the issue.

I'll try to get trace this afternoon. But I've problem to update WebView to 144 on my computer (updated on some other employee computers). I've Edge 144.x, but WebView freezed on 143.x... I'll try to somehow force upgrade.

@navneetrathi-msft I've trace files collected (about 65 MB zip). Where could I upload it? It's too large for Github. Thanks

You can upload the file to a one drive or some other cloud and share the link for us to download.
