What is native canvas and what happens when I disable it?

I disabled it to see if it will fix a dual display issue I'm having, but I'm curious to know what it actually does. Anyone know?

So I'm using a 27" 2020 imac with a second display. It seems that when I've been using photoshop for an extended period my whole system freezes. My second monitor goes green and my imac goes black. I suspect my graphics card might be wigging out so I found this workaround. https://helpx.adobe.com/photoshop/kb/photoshop-cc-gpu-card-faq.html

It mentions disabling native canvas. I still need more time to see if this is the fix, but wasn't sure what I was losing by turning it off.

As I understand it, "native canvas" means what you see on screen is rendered using OS-native APIs, i.e. Metal on Mac, DirectX on Windows.

Disabling it means reverting to the old OpenGL APIs.

OpenGL is no longer supported by Apple and Microsoft, hence the entire GPU code is in the process of being migrated. That's a big undertaking and predictably a rather bumpy ride. Glitches and bugs will happen.

Once it's all done and thoroughly tried and tested, the "disable native canvas" checkbox will be removed. In the meantime, it's important that any problems are reported under the "Bugs" subsection. If checking the box makes the problem go away, it needs to be fixed permanently.

Unless I misunderstood the whole thing.

When you disable native canvas photoshop goes back to functioning properly without glitches and bugs.

It should be a beta only feature reserved to betatesters but godknowswhy they impose it on paying costumers.

Odd; I have the option OFF (I'm not using Native Canvas) and there are zero issues and greater speed; care to explain that?

What is to explain? Leave it off - it's better this way.

E.G. I can't batch process more than 5 pictures at a time when that crap is active.

Thanks for the link. I'm still not sure what it doesn't after reading it. Looks like it has something to do with 3D in PS. I disabled it in hopes that my mac stops getting a green screen after hours of working with two monitors.

It's legacy behavior that is going away.

Greens screen, can you tell us more or provide a screen capture?

First, try disabling GPU in the preferences (Preformance tab). Any better?
If not, recalibrate and build a new ICC display profile, the old one might be corrupted.
If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.
If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it.
