Frequency Separation - strange result on Apple M1 with activated hardwareacceleration

Recommended Posts

Dear Affinity-Team,

first of all: congrats to the new versions of your software-lineup - your work is highly appreciated!

My first try of the frequency separation filter with V2 of Affinty Photo on an Apple Macbook Air M1 OS 12.6.1 (hardware acceleration on) has produced a strange result (screenshot attached - left V1 / right V2 - high frequencies shown: looks like a spectogram). This happen with the gaussian variant and values over 5 pixel - 16 or 8 Bit doesn't matter. If hardware acceleration is off, the result is the same as for V1.

If additional infos are needed, just let me know.


Best regards

I have the same problem. Frequency separation was not working in the first V2 release, then it was working in 2.0.3. Now it's broken in 2.0.4 again 😞

MacBook Air M1 , macOS Ventura 13.2, Affinity Photo 2.0.4
