There is a problem with the processing of the Unsharp Mask filter in Photoshop ver. 2022.
I applied the USM filter to the attached usmtest.png with the settings shown in filter.png in ver.2021 and ver.2022.
You can see that there is noise in ver2022.
Preferences > performance GPU: off Multi-threaded compositing: off Preferences > Technology Preview Native canvas: off
I have tried all of the above with no improvement.
The Japanese forum post shown above reports that "results vary by PC".
Open usmtest.png in ver.2022 (23.3.2) and try Amount: 300%. Radius: 5.0 pixel Threshold: 0 level and apply the USM filter to enlarge the processed result. If noise appears, please let us know the configuration of your PC.
Noise appeared on iMac5K 2017 (Big Sur / 64GB memory / Radeon Pro 580 8GB memory).
It does not occur in Photoshop 2021/2020/2019.
