Major image corruption on screen when using Photoshop 23.5.0 with M1 MacBookPro/Monterey

Corey,

I have what appears to be the same problem with PS 23.5 on a Windows 11 platform.  I unchecked Multithreaded Compositig and restarted PS.  I didn't see an soption for "GPU Copositing" either under Performance or Performane>Advanced Settings. (Could this perhaps be the "Use Graphics Process" option on a Windows platform?  On the assumption that this was the case, I also unchecked "Use Graphics Processor".) I restarted PS and then opened a large (2.35 GB) psb file.  It took 11 minutes to open the file and even then the tools were not active.  I waited another 5 minutes before opening the Windows Task Manager.  The file was unresponsive, so I ended the file and PS.  By comparison, PS 23.4.2  opens the same file (with both Mutithreading and GPU options CHECKED) in about 8 minutes (still too long, but better), and was also slow to enable editing.  Release  22.5.9 took about 10 minutes to load and but was mmediately editable.  I know this is a very large file, but it should still work.  23.4.2 works reasonably well for smaller psb and psd files, but there is clearly some kind of problem here.  I use a lot of smart objects and layers/masks in my work and it is essential that these functions work quickly and smoothly.  As it is, I have rolled back to 23.4.2 and kept 22.5.9 around for the larger files.

Please let me know if I can provide any additional information.  PS is a critical part of my photography work flow and I would like to take advantage of the improvements.  As it is, the new version is essentially unusable.
