Using the CRenderer off-screen rendering method for WKWebView results in a blank screen for the web page content on the iOS 16 system version, but it can successfully obtain the web page content screen on the iOS 18 system version. I need a solution to achieve the display of web page content on the 16 system version, with a frame rate of more than 60 frames per second.
Using CARenderer for off-screen rendering of WKWebView results in a blank screen for the web page content on iOS 16 system version.
In addition, I would like to know if the CARenderer off-screen rendering method for WKWebView is effective when using the iOS17 system version?
