Hi everyone, I'm building a Gear VR app in Unity and when I download an image from web (with WWW constructor) and I print it in my scene, in an UI image or in an inverse sphere, for a second the frame of my view is blocked in a specific point and I see black all around. My version of Unity is 5.4.2f2-GVR13 and work with OVR Oculus Utilities for Unity 1.10.
The image file size itself isn't the culprit for stalling the app, but rather the process that sends the image data (pixels) to the graphics memory. The larger the image is (in pixels) the longer it takes (stalls).
