[Live Depth of Field blur causes white frame around the image]

Thank you. While focusing only the modified values, I didn't notice that option was missing at non-live version. So couldn't get why they were different.

[Live Depth of Field blur causes white frame around the image]

Applying live depth of field filter to my background image causes a white gradual frame of 4-5 pixels around the whole image, on all edges. The exported images also has the buggy white frame, so it is not about the preview. The regular (non-live) depth of field filter does not cause the same problem and it works as intended. I'm attaching my affinity photo project file and a sample jpeg export for reference.
