  1. Resolution Note (2019.4.X):

    To fix the image filter issue due to asymmetric FOV (on the developer side), the image filter needs to account for asymmetric FOV and use the projection matrix to derive the offset center. For more details, see this blog post from Oculus:

    Is there any update on that issue or ETA about a resolution? This is a regression, has been open for a year, and spans 3 releases. Blitting with offset/scale is essentially for some applications involving single-pass stereoscopic rendering due to the double-width buffer.
