hi,

 

after using depth of field blur in affinity photo, my image showed lines and squares and some tiny dots.

large squares as seen in the affinity u.i. (see .png screenshot); small squares after exporting the file as .jpg (see .jpg attachment).

i saved the .afphoto-file, but that's over 100 mb, so i can't upload it here.

is this a bug or am i doing something wrong?

trying to reproduce the problem, i discovered that lines, squares and dots only appear when using the clarity slider of the depth of field options.

Hi illusie,

We are aware of a similar bug with this filter.

Can you give us some more details?

Are you using the Live Depth Of Filed filter or the regular one from the filters menu?

If you are using the Live Depth Of Filed filter, do you have Preserve Alpha check box checked?

 

Thanks

yes, i'm using live dof in this case and as you can see in the attached screenshot preserve alpha is checked.

 

the problem appears to be in the clarity slider and/or the preserve alpha checkbox. lines and dots disappear when i either slide the clarity slider to the ultimate left (value 0 px) or when i un-check the perserve alpha.

 

just found out: there's one blending mode where the problem doesn't appear: 'lighter color'. but i'm not sure if this wil be the same with other photos.

Hi illusie,

Thank you for the screenshot, it was very helpful.

This is a known bug triggered by the Preserve Alpha checkbox. If you disable it the transparent artefacts should disappear.

It's already logged and should be fixed soon. I'm marking this as a duplicate bug. Thank you for your report.
