Maximum/minimum blur preview fix needed


Recommended Posts

The previews for both Minumum and Maximum Blur do not show the correct result after you hit apply. Minimum Blur goes significantly darker after applying and Maximum Blur goes much lighter (producing a halo the more blur is applied.) See xamples attached.

What is your Zoom level? If you're viewing at less than 100% zoom when you press Apply you won't preview the actual result due to the mipmap rendering technology that the Affinity applications use.

The Zoom level is 100% - fully zoomed out. I think the problem is more pronounced when 'circular' is checked. It also seems to depend on the content. Experimenting with other photographs I find that the preview/apply difference is less pronounced in some images.

"Fully zoomed out" is not 100%, usually. What does the Navigation panel say the zoom level is? 

Or, try Ctrl+1 (Windows) or Cmd+1 (Mac) to set the zoom to 100%.

Ooooooh, doh! This is why I don't earn the smart money ☺.

Yeah, once I've got the navigation set to 100% it previews fine. Shame it doesn't preview accurately when viewing the whole image, though.

Thanks.

Tim
