Objects Not Moving, Disappearing, Anomalies Abound...

I've been using PhotoShop consistently since version 1.0, in 1990, when there was one undo and no such thing as layers.  I've got 35 years in the program and I'm pretty sure I've never seen anything as buggy as these past view iterations.  One problem I've been having, among several, is that when I select a layer with an object, choose my move tool and try to reposition the object with my arrow keys or cursor, it doesn't appear to move, though it actually is.  I can only see how much the object moved by toggling the hide (eye) icon on the layer, blinking it off, then back on, after which I can see how much the object moved.  It almost seems like a rendering issue, an inadequate system graphics card, but I'm running a Mac Studio Apple M2 Ultra, a $6k setup with more than enough under the hood to satisfy any needs the app might demand.  I routinely run audio and video production programs with no problem.  My files are on a 2TB SSD external thunderbolt drive, so that shouldn't be a problem either.  I'm using PS version 27.0.0 through a Creative Cloud subscription.

Is this a known bug, or am I missing something?

Thanks.

Follow-up:  I just went back into my project to continue working, needed to hide the backgound group of images for a moment, tried to unhide that group and it wouldn't come back at all.  Not a "delay" in showing: it wouldn't show at all.  Was about to close and reopen the file when I reduced the view size, command/-, and it came back.  Somthing very wrong here.
