QML WebView - Windows Woes?

[Malachi]

Hello all,

Our Qt6 app uses WebView in one isolated circumstance to assist in OAuth flow. It's basically 2-3 pages. Typical enter phone # , captcha, TOTP entry.

On Debian and Android it is working perfectly well
On Windows 10, it runs intensely slow and is fails to execute the captcha, thus impeding the process

Seen in console are quite a few "js: Uncaught (in promise) Timeout (u)"

Can anyone offer clues? Thank you
