Our iOS app is use WebView, and viewing our service web site.
However user reporting "image drawing only white" in recently.
In this case confirmation only on iOS 12.3.1 devices, it is not always. Only some times drawing white image.
Image file format is PNG.
I connected problem device to Mac, and checking web inspector on Mac Safari.
But image is normaly viewin in web inspector.
This happen only does iOS 12.3.1.
lower version OS is no problem.
But Safari is don't have this problem, on same device.
I think it seems to be WebView bug.
WebKit is any different point on Safari and WebView?
Anyone have same happen? and any solution?
I checked and confirm that our app in use UIWebView class.
I just learned that it was this class deprecated at iOS12.
My problem reason is it?
