Rendering differences between 4.7.6 and 4.8.3 on mobile?

Hi all,

I’ve noticed the following issue after bringing a project that’s fine on 4.7.6 to 4.8.3.

See the attached screenshots.



What might be the cause of this kind of rendering problem?
What’s even more strange is that this is not occurring everywhere. At some area the wall just showed up totally fine.
For example, the wall at the top of the door rendered fine and the wall at top right corner rendered partially…

The project is running on an iPhone 6 Plus, iOS 8.1.2.


I would like to add that things seem like working correctly on iOS 7.0.4.

I’ve noticed that if I switch off Metal for iOS 8 devices, everything seems normal. Also as I’ve commented on another thread, depth of field will crash if Metal is enabled but won’t crash if it’s disabled. Maybe a bug with Metal RHI?
