minesworld commented 2 years ago

Description

webView.CoreWebView2.GetDevToolsProtocolEventReceiver("Overlay.nodeHighlightRequested").DevToolsProtocolEventReceived += OnOverlayNodeHighlightRequested;
webView.CoreWebView2.GetDevToolsProtocolEventReceiver("Overlay.inspectNodeRequested").DevToolsProtocolEventReceived += OnInspectNodeRequested;

await webView.CoreWebView2.CallDevToolsProtocolMethodAsync("DOM.enable", "{}");                
await webView.CoreWebView2.CallDevToolsProtocolMethodAsync("Overlay.enable", "{}");         
await webView.CoreWebView2.CallDevToolsProtocolMethodAsync("Overlay.setInspectMode", "{\"mode\":\"searchForNode\",\"highlightConfig\":{\"showInfo\":true,\"contentColor\":{\"r\": 155, \"g\": 11, \"b\": 239, \"a\": 0.7}}}");

receiving the inpectNodeRequested stops working after some time or it will crash.

Repro Steps

  1. Sample VS2022 project in https://github.com/minesworld/WebView2Tests

  2. Crash reports (copy & paste) in folder crashes

  3. Build & Start WinUI3 project

  4. Select some options: 4.1. "Async": second async call to intialize the WebView2 4.2. "DT-Overlay": enable Developer Tools Overlay mode 4.3. "DT-Event": receive Overlay events 4.4. "WebMessage": run a JavaScript interval function and receive them 4.5 "Navigation": receive NagivationComplete events

  5. Press "Start" Button

  6. watch Debug/Diagnostic output

  7. if DT-Overlay & DT-Event checked and clicking does not bring up a new output line, click "No DT-Event" button to have this logged

  8. do some clicks, wait, use another app, etc. . Crashes come unexpected, but it seems to depend on the website (my "favorite" for crashing: https://www.bundestag.de/abgeordnete/biografien )

Besides the crash:
