Issue description

in a specific combination of settings and assets, the temporal MetalFX upscaler breaks

Steps to reproduce

in a 3d scene, do the following:

• use Mobile renderer
• enable dof on the camera
• put a mesh in front of the camera that is screen-reading
• enable MetalFX (Temporal) upscaler in the project settings (scale factor 0.5 as example)

these 4 things in combination create the bug. as soon as one of them is missing, everything works
all other upscalers do not have this issue.

the bug looks like this:
