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.
