Short description of error
2.93's DOF sometimes confuses which parts of view should be sharp/blurred. Screenshot, video clip and simplified .blend attached to check out.

Exact steps for others to reproduce the error

open .blend file
use mouse scroll wheel to zoom in/out viewport (camera stays locked)
you should notice artifacts disappear/appear depending on scrolling

I could not reproduce on my AMD workstation. I will have to test on another hardware configuration.

this is normal. that are the different distances from the camera.
in the old system it was the same

Could you explain it further?

So im not a developer but i think of my use of the dof that the dof has steps. So i think that has to be a feature to interpolate the steps ore blend the steps into each other. Am i right?

No idea, but =<2.92 didn't have these artifacts, it's new. Dev mentioned tiles not being calculated correctly, so maybe it's a screenspace thing?

@fclem Any successes in reproducing issue on another hardware?

@fclem That's fantastic, just checked out .blend file and I don't see artifacts originally reported in first post. However, I've noticed some strange outlines - their appearance depend on how you zoom in/out in viewport and on value of F-Stop in camera settings. Is it an known issue? Enabled Jitter in DOF settings solves it, if it helps.

At 0.2 F-stop:

At 0.1 F-stop outliner dissapears from character and appears on window frame:

EDIT:
Recorded behaviour:

EDIT2:
Seems this outline artifact doesn't seems to be apparent in renders

I've noticed also jagged artifact, camera height position and viewport zoom in/out affect it - there's recording:

Forgot to add blender/system info - it's for this and previous post:

EDIT:
I've quickly tested DOF parameters in Render properties:

lowering or upping Neighbout Rejection mitigates it (albeit with different looks)
setting Denoise Amount to 0.95-1 mitigates it
