Details

As of bug 593618, the D3D9 layers backend validates the entire bounds of the visible region. However, this is subtly incorrect: we could be validating pixels which (while not currently visible due to some other layer occluding them) may make the entire layer non-opaque. To fix this, we need to draw the visible regions individually out of the texture. (We can then remove validating the entire bounds of the visible region.)
Severity: normal → S3
