[Problem/Bug]: Webview2 Memory Leak when Opening SharePoint #5447
Description
What happened?
Microsoft Edge consistently freezes, lags, and becomes unresponsive when opening multiple SharePoint Online tabs. Task Manager shows the Edge Browser process rapidly climbing to 5–6+ GB RAM, after which all tabs freeze or crash. This repeats reliably.
This behavior only occurs on Edge/WebView2, not Firefox; Firefox loads the same SharePoint pages smoothly.
This strongly indicates a Chromium/WebView2 rendering stack issue, not a hardware or SharePoint problem.
Importance
Important. My app's user experience is significantly compromised.
