Why have I had to disable my GPU in Photoshop in order for the images not to be scrambled?

Thanks for letting me know what a psd file is. I've only been using Photoshop professionally since 1996!!

There is no graphics card on new Mac Studios. The GPU is assigned processing within the CPU. There is no physical card.

When I disable the GPU in Photoshop in order for it to display properly, it is in fact part of the processing power that I am switching off.

Processing power that I seem to remember cost rather a lot of money.

Anyway, back to the point. Photoshop is not communicating properly with the M1 chip, that's about the bottom line.

Photoshop  for Apple Silicon

Run Photoshop faster in native mode on Apple computers using the Apple Silicon M1 chip. 

As of March 2021, Photoshop now runs natively on Apple computers using the Apple Silicon M1 chip with 1.5X the speed of similarly configured previous generation systems.

Photoshop performance under Ventura M1 on my Mac Studio has been dire. The only way I have been able to stop my psd files appearing scrambled or just plain black has been to disable the GPU.

What exactly have I paid for if I have had to disable the GPU in Photoshop? On what is arguably a machine built specifically for Photoshop?

PSD files are the native file format of Adobe Photoshop.

The Mac Studio only has one GPU—

Is your third party software up to date and compatible...? I would start there.
