Product:Safari Product Version:iOS 10.3.2
Classification:Serious Bug Reproducible:Sometimes
 
Summary:
After using an iOS device for a while (particularly iPad) webviews can go black and not function until rebooted. Rarely will it recover without a reboot. After this any Safari instance or WebView will be black. Mail contents included.

Steps to Reproduce:
1. Use iOS device for weeks
2. Be sure to regularly use webview driven apps, in my case: Tweetbot, Mail, Mr Reader, Safari, Facebook

Expected Results:
Webviews continue to render visibly.

Observed Results:
Webviews go black, nothing is readable. Reloading doesn't change anything.

Version:
iOS 10.3.2 (14F89)

Notes:


Configuration:
Generally was only happening on my iPad Pro 9" but it gets used for web type content more than my iPhone 7+ does. 7+ also has had it happen.
