Photo Goes White After Certain Point of Gaussian Blur in Affinity Photo

[TheScavnger]

I have been trying to add gaussian blur to several of my images but they all have the same problem where if I go beyond 9px everything turns to white. I have added screenshots of both state along with my performance settings.

Welcome to the Serif Affinity forums.

That works fine for me, in the main workspace, though I do get a white artifact in the Navigator panel just below 11px:

Suggestion: try disabling Hardware Acceleration in your Performance Preferences, and see if it fixes things.

Edit: I also see a white artifact, sometimes, in main workspace after I restarted Photo (actually, with Photo Beta). So for me sometimes it's in the main workspace, sometimes only in the navigator.

Thank you so much! That worked like a charm!

I am just curious as to why are you only utilizing 2 GB of your RAM?

I moved the slider accidentally lol. Now I changed it back to the default 4GB.

Hey TheScavnger,

You could try using DDU to fully remove your graphics drivers and do a clean install. What GPU do you have and what driver version?

Hi, I get the a similar effect with a white square appearing at higher values using guassian blur from the filter menu. However adding gaussian blur either as a live filter layer or from layer effects works fine even at 100% radius. This was using the latest beta 1.10.0.1104 with hardware acceleration enabled. I did not get the same effect on the poroduction release 1.9.2.1035. Guassian blur worked fine using all three methods. I flagged up a similar problem some time ago using Frequency Separation with high guassian blur values. This still exists in the latest beta.

I have a similar problem when I use Gaussian blur in the "layer" tab, once Hardware Acceleration is off (Gaussian blur 0,1).

Hi @GG0,
Welcome to Affinity Forums
Sorry the delay getting back to you. We have been a bit busy. I'm having trouble reproducing this on my system. Are you still experiencing this issue in version 1.10?
