Crashing After installing PS 26.3.0. Getting weird display issues on certain layers in photoshop.

[gSauce]

Crashing a lot after install of 26.3.0. Also getting weird display artifacts like retangular shapes baked into the layers that seem to come from no where. It appears the layers became corrupted. Went to a previous file version and the layer is fine. Im running a iMac 2020 3.8 GHz 8-core intel Core i7. AMD radeon pro 5500 XT 8 GB graphics card. 128 GB 2667 MHz DDR4 ram. Plenty of storage. OS Sequoia 15.3.1. Ran for years on OS Catalina and Photoshop 23.5.2 with no issues. Profesional work everyday on large files. No issues. Until 26.3.0. Does is not like Sequoia? Is there a more stabe version for sequoia right now? Four years back I was told by adobe support to run Catalina with specific PS versions an they were not the latest and it was fine. Now I can get my work done.

After a quick scan of the Photoshop system requirements, I can think of a place or two in Settings you should check:

Ps>Settings>Performance>Memory Usage: available RAM? Let Photoshop Use what percentage?

Ps>Settings>Performance: is Use Graphics Processor checked?

Ps>Settings>Performance>Advanced Settings: did Photoshop disable (uncheck) and settings?

Support for Metal on Mac, iPad, and iPhone ?

Thanks for the reply. So in the GPU mode info panel, GPU mode was not selected. Graphics processor compatability check showed up good. Plenty of ram, Metal available, and GPU detected.

This sounds suspiciously like the AMD GPU is acting up. Unfortunately you can't update the driver separately, as you can on Windows, so unless a MacOS update fixes it, you're stuck with it.

You can try to go into settings > Graphics Processor Settings > Advanced, and uncheck GPU compositing.

You can also try to uncheck Multithreaded compositing in the main performance tab.

Worth trying this perhaps?  Does five years count as  an 'Older GPU'?

Thanks for the reply to all. I believe I did hear about unchecking "GPU compositing' in the past. We may Have set up our work machines that way. I can try it. I can also try unchecking "Mulithreaded compositing". The crashing seems to have slowed down but there was definitely something going on with graphics and transfering as far as corupting layers. It would go away on some versions then get baked in on others. I have had that happen in the past and its a nightmare. Like having a ghost in the machine you can't find. I first noticed it here while changing a layers display mode. It appeared to bake in a color correction. It disappeared on several file versions after reopening the files but baked it self in on the others. Its unsettling. But for sure something is not right. I try those fixes.

Hi

Ok so I tried all the above and my crashing contiues. I can barely get my work done. What a nightmare. I've updtaed my drivers and tried running nothing but photshop and its not good. Tried using different scratch disks. I reinstalled v12.5.0 and v25.12.1 to see if it was any better than v26.3. No luck. It appears to crash often when I enter into making any color adjustments to a layer. Dozens of crashes today along those lines. This has become a series problem. I'm hoping I can get some help. Tried turning off GPU compositing but it didn't help. During several crashes my speakers will sound out this weird crackling noise. Never heard it in the past. It also did that sound when I installed OS sequoia.
