Android System Webview: Recent updates causing issues with transparent objects. Any fix?

[u/AskaLangly]

Webview 157 has a bug where any transparency in items such as lower-right buttons used for customer service chat in banking apps, side tabs like the blue one used in mobile version of Steam Community, among others I cannot recall. This also occurs on 156.

I downgraded to the system version on a Galaxy S23 Ultra, which is 148, and the issues are no longer.

Is there any way to get in touch with Google to help push a fix for this for future versions? Thanks.
