ProPhotoRGB images don't render properly with 'Use Graphics Acceleration' enabled

  • Updated 8 months ago
If you open a ProPhotoRGB image in Photoshop with 'Use Graphics Acceleration' enabled then it won't properly render transitions between one colour and another; it steps between colours in bands. Disable 'Use Graphics Acceleration' and it renders properly.  Change to any other colour space and it renders properly.

Easy way to demonstrate it is to create a fill between black and white, which guarantees that you'll be able to render all of the colours in the image on your display.

It's not an option to keep Graphics Acceleration disabled all the time because some filters (e.g. Liquify) are only available when hardware acceleration is available.

I reported this bug back in March of 2016 (cases 0187639066 and 0187678577) and other people had reported this same issue long before I did.  It's really about time this was finally fixed.

I seem to be unable to reproduce the issue on 
Adobe Photoshop Version: 2017.1.0 20170309.r.207 2017/03/09:23:00:00 CL 1107877  x64Number of 
Operating System: Mac OS 10.12.3

You may have to provide more information (versions, Advanced Settings, ...).

Adobe Photoshop Version: 2017.1.0 20170309.r.207 2017/03/09:23:00:00 CL 1107877  x64
Operating System: Windows 7 SP1

The attached image demonstrates the problem pretty well.  The out of focus bokeh is blotchy when the graphics acceleration is on, but is properly rendered when it isn't,  Note that you'll need to restart PS each time you switch graphics acceleration on or off.

Don't know if this impacts Mac as well, but I experience the same issue on multiple PCs with different (supported) graphics adaptors, and I'm not the first person to have reported this either.  It's been complained about for a number of years now,

It's hard to tell what's going on in the image you've provided... could you post the non-blotchy version as well?

Sure.  Look at the transition from the black areas to the left.  Here's a comparison where I captured screenshots of how Photoshop is rendering the same image with and without the graphics acceleration enabled.  Color space is unchanged, as is the image.  This is simply the difference between enabling and disabling graphics acceleration.

Thanks, that definitely shows the issue. I'll see if i can reproduce on a mac and hopefully someone from Adobe can also take a look.

So I'm rather disappointed to see that yet another release of Photoshop still hasn't resolved the issue, despite it being raised by me over a year ago, and by others long before me.

Yet another release of Photoshop and still it can't properly render ProPhoto RGB images when GPU acceleration is enabled.  And zero replies from Adobe since I sent them the test files, which demonstrates how much they care about their subscription customers.

Yet another version of Photoshop released that I'm paying a subscription for, and still ProPhoto RGB doesn't work with GPU acceleration enabled.  Adobe, are you listening, or do you really treat your paying customers with this much contempt?
