Have a look at these images. This happens in Safe Mode, in Normal Mode, with the GPU switched on or off and whether it's Legacy Free Transform or not. Everything fractures as I move it around. These are screengrabs from screen recordings. The file size is 140Mb which for me is small to normal.
This is concurrent with generally poor performance (which doesn't improve in Safe Mode) where controls are sticky and there is a micro delay on every mouse click.
Occasionally if the GPU is activated the images appear fractured or black upon opening and simply have to be closed again. This only happens now and then.
I am also having bad performance issues and crashes in Illustrator. On tiny <1Mb files.
The only program that is running smoothly on my Mac Studio is Cubase. Anything graphics-based is slow.
I am running a Mac Studio M1 Max 32Mb, Ventura 13.3. I have carried out a diagnostics check (normal) and tried Safe Mode, GPU on and off (same issues).
