Photo 2.0.4 - Converting a document to 16-bit breaks colors

[Alex_M]

As the title says. Please see attached the screenshots and the attached .afphoto document where you can test this. If I delete the Color Balance adjustment layer, the problem goes away.

No problems with colors breaking on my Mac using AP V2.0.4, with or without removing the Color Balance adjustment layer.

I am not aWindows user but this might be related to issues in the Windows version with some GPUs & hardware acceleration. Maybe try switching that off & seeing if the issue persists?

Thanks for the quick reply. It was indeed due to the hardware acceleration. I turned it off and it works fine now! Hopefully the dev team looks into this.

They have been doing that for a very long time. The big problem is there are so many different combinations of Windows GPUs & drivers for them that reliable hardware acceleration may never be completely sorted out.

Perhaps ironically, on the Mac side there are far fewer GPUs to support so it is rare for there to be any problems with them, although it does happen on that platform too.

Hi @Alex_M,

Thanks for your report and your file provided, I've tested this here on Windows with Hardware Acceleration enabled and I'm not seeing the same issue currently - however this appears to be a very similar issue to the one reported below, which was confirmed to be due to the Nvidia driver version or a virtual colour profile being applied to your monitor:

Can you please try the steps described to set your monitor colour profile through Windows, as well as removing your current drivers and installing the latest available, directly from Nvidia?

Many thanks in advance
