Brush and zoom in & out canvas are super lagging with eGPU - MacOS 12.3

[Claude2212]

I set up the new MacOS yesterday and my paint tool and canvas(zoom in&out, moving) are not smooth as before.

Hardware: Macbook Pro 15.4 (2019) i9, 560X, with a eGPU AMD 5700XT, LG 32UN650 monitor

also, I tried connect to my monitor without eGPU(5700XT), it gonna smooth like before. But my eGPU works well with other software (Blender etc). So I think it's just a problem with Photoshop.

I can confirm that this is a compatibility issue between eGPU and Photoshop (Under MacOS 12.3). And now I have to use the built-in graphics card (560X) to work
