33090643: Significant Visual Distortion In Simulator Rendering

openradar-mirror commented 7 years ago

Description

Summary: When using the iOS simulator (Xcode 9 beta 2), significant rendering issues are commonly observed. Initially, I believed this was related to errors in an application I building. However, I’ve been able to observe the issues in system apps (most easily observed in Photos).

Steps to Reproduce:

Launch iOS simulator from Xcode > Open Developer Tool > Simulator menu item
Launch Photos app (occurs in system apps as well as third-party apps)
Scroll around randomly; observe flickers and glitches in screen rendering

Expected Results:

Screen should never draw inaccurately

Actual Results:

Frequent screen glitches and flickers are observed
