When High Quality Gaussian DoF on Mobile is enabled, the entire screen is always blurred.
I confirmed that it works properly in 4.24.
Also, I confirmed that adding the modified CL of [Link Removed] to 4.25.1 does NOT solve this issue.
Result: The whole screen is blurred
Expect: Dof works properly
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-94444 in the post.
