Affinity Photo 1.7 crashing While using Lens Blur

[swastiverma 1]

I am trying to use Lens blur on Affinity Photo. After opening the Lens Blur Adjustment, as soon as I click on Radius Affinity Photo crashes. I tried using Depth of Field and Gaussian and they work fine.

Let me know if there is any issue with the same?

Hey swastiverma, welcome to the Affinity Forums.

Rotating seems to work but if I type in a value and OK it, it will crash. I'll log this with the developers—thank you.

My experience so far is that, while it doesn't crash, it's horribly slow. Also, when i apply a mask to the filter in order to paint out some of the effect, the brushing behaviour is very poor.

I can't even really get as far as that without it crashing. Perhaps whatever is causing the crash is causing poor performance for you. A screen recording may help if you could provide one.

The problem is that, when i make a recording, the recording kind of crashes (when i stop recording nothing is saved).

What i did notice while trying to record is that selecting a high Radius value (e.g. 800 px) seems to have a big impact. As long as that value is low there's not a real problem (just a little bit slow). As of a value of 200 px the performance really starts to deteriorate. I'm using images of an approx. 1080P size.

Note: i've also noticed that my fan keeps running after this exercise, even after i have quit Affinity Photo (it's not there any longer in Activity Monitor). Normally, it will go back to 'silent state' after a while.

If that crash gets fixed, it may sort out whatever performance issues you are seeing. I will add your feedback to the bug report!

I am running AP 1.7.3 on Mac OS 10.15. AP crashes when I apply a blur.
