Image in Library view is normal, in Develop its corrupted

Question

As I have been using Lightoom Classic v13.3.1 Build [202405311538-6d7c0308] on MacOS Sonoma 14.5 (23F79) images have been artifacting and corrupting in Develop mode as I work. The original file is untouched but all of my develop settings are ruined and I cannot even export a clean image. This issue has happened sporadically and I cannot seems to figure out why it's happening. I'm not sure if it is a preview issue, a caching issue (I've cleared my cache and restarted), or anything else. I have even tried undoing all my edits to see if it "repairs" the artifacting/issues. Nothing works. Also, if I move along and try to work on more photos every photo I attempt to edit corrupts like this.

Please try to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue. Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

Another step is to try to reset the Lightroom preferences.

It's recommended to backup your preferences before you reset the preferences to the default settings:

If this doesn't help, please provide also a copy of your 'System Info'. This can be get from the LrC Help > System Info menu item. There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.

If your Mac computer has an AMD GPU, then it's very likely that you're experiencing the bug discussed in https://community.adobe.com/t5/lightroom-classic-bugs/p-gpu-develop-edit-view-amp-export-artifacts-after-14-4-1-update-amd-only-affects-cr-lrc-amp-lrd/idi-p/14563606
