Now downloaded and installed Photo 2.5 Beta and no sign of the artefacts when loading Raw file. Thanks Guys.

Hi Guys, I installed Photo 2.4.2 and tested. Hardware accn ticked and raw output format at 16 Bit resulted in artefacts Hardware accn unticked and raw output format at 16 Bit -no artefacts Hardware accn ticked and raw output format at 32 Bit HDR - no artefacts Hardware accn unticked and raw output format at 32 Bit HDR - no artefacts For now I'll just leave accn unticked.

Yes, loaded fine after disabling.

No, its Sony A7 RIII and ARW file attached. I have also opened the file in Affinity 1.10, saved as Affinity file then re-opened successfully in Affinity 2. Thanks DSC00515.ARW

sorry, and I have output at RGB 16Bit

Hi, I have the exact same issue with 2.4. which I updated today.

OK sorted with a re-install.

I have just upgraded Photo to 1.8 on a Dell laptop. I now experience issues with tone mapping which goes straight to "Detailed colour toned down" preset and does not permit choosing any other preset. Anybody experienced this and have solution.
