iOS 17 beta: problem with transparency on website

Hello,

We're testing our app using iOS 17 beta to see if there's any problem, and we encountered an issue with an image rendered using HTML5 canvas having the alpha layer turning to white (See screenshot below) This happens not just our website but to other website as well. Both in UIWebView and Safari Browser.

Is this going to be fixed before the actual release of iOS 17? or do we have to tweak our code somewhere in order to fix this?

Thanks!

Regards, Byron Bautista

There seems to be a problem with all transparent png-images, they are rendered without alpha until interacted with. So the whole web is partially broken (even apple.com) so I think it will be fixed :)

I've filed a bug in the feedback assistant.
