p.1 #1 · FYI: DxO Photolab 5.2.1 for macOS has issues with output quality
FYI I encountered some issues with fuzziness of the output from this version 5.2.1. DxO kindly made v5.2.0 available via their download server for those like me who do not keep older versions of the DMG files. So you can download and revert back to version 5.2.0 which seems to not be affected.
I have a M1 Macbook and don't know if the issue affects Windows version or intel Macs of just certain types of RAW files. It certainly affects my Alpha 1 compressed RAW files.
