What happened to Photoshop? I only see a green screen after the update

Hi @defaultu90rc28vgqgh 

I'm copying this from ACP @davescm , who has said it well:

"Adobe is updating the core graphics functions in Photoshop. This is driven by the operating systems of Apple and Microsoft in which the old Open GL functions are being removed in the case of Apple, or deprecated in the case of Microsoft. This means that the graphics functions that have worked for years must be rewritten to use Metal and Direct X. At the same time, Adobe is sensibly updating those core functions to deliver the additional speed we require to handle the very large files of today.

"Deactivate Native Canvas forces the GPU to use the older GPU functions. After any GPU driver update, which could be delivered via your operating system, or after updating Photoshop, uncheck it and try the new functions again.

"Note though that some older functionality in Photoshop, such as 3D and Lighting effects, still relies on the older Open GL graphics and so also need Deactivate Native Canvas to be checked ."
