Weird Photoshop OpenGL/CL issue.

[Ganktank]

OK so I'm at my wits end with this one. I have searched through the forums and nothing seems to be the fix I need.

I am running PS CC 20.0 (this is the 2018 Version I assume)

When I open an previously saved Doc Rotation Tool works, When I open a new document or save and reopen a document Rotation tool doesn't work I get the

"Could not complete your request because it only works with OpenGL enabled document windows."

I literally have 2 documents open where on one the Rotation tool works and the other it doesn't work at all... Not sure what is going on, slightly loosing my mind.

I have >checked the preferences >I have updated my Nvidia driver. With PS currently open one file I can use the rotation tool, the other open file on a different tab, in the same PS application  I can not use the rotation tool.

Any advice would be nice. I'm guessing there is some preferences saved on previous files, but I don't see how that would make any sense when opening the file.

No Photoshop version 20 is Photoshop CC 2019.  The installer may have removed your CC 2018 if you did not use the advance install option and uncheck remove previous version.  You can reinstall CC 2018 using the Creative Cloud Desktop application.  You CC 2018 preferences should still be on your machine.

Thanks for the information, but it is irrelevant to the outlined issue.

For CC 2019, A preferences reset should help:

What would this do for me in the long run? Doesn't fix the issue FYI

I was hoping it would run the GPU sniffer among others.

If you have dual card system, uncheck Automatic graphics switching.

Checking to see if this is a thing on Win10,

I am using a Dual Card Set up, with a Dedicated card for my Cintiq. Keep in mind that this works for some files and not for others, this is what really has me dumbfounded. One Photoshop file I can use the Rotation tool Perfectly fine, another photoshop file... I can't.

As your original message says, OpenGL is enabled per document window. It's not global.

So apparently you have some marginal conditions here, causing it to behave erratically. Prime suspect is dual video. This is known to cause problems with Photoshop, and is officially warned against.

Just consider it. This has to be loaded from the video card in every instance - but which one?

[Ganktank]

ahhhhh that makes sense, I'll look into it Thanks. I'll get back to you later today.

Hi

See section 7 and 8 here on the use of dual GPUs with different drivers :

Troubleshoot Photoshop graphics processor (GPU) and graphics driver issues

The aim is to ensure Photoshop only sees one driver
