Preview image not appearing or is fractured in Photoshop 21.2.5 on macOS

[BillFredericks]

Hello,

example: I have an image im editing, and I want to change levels. When I move the slider, either the image disappears for a while, or it comes up quickly but fractured in blocks and will slowly populate to full image. too slow. never had this issue before. Thank you, Bill

Hi,

We're sorry about the trouble with Photoshop. Would you mind telling us the macOS version you're working on? You can try disabling the option to Use Graphics Processor from Photoshop by going to Preferences, then Performance. Once done, quit & relaunch Photoshop to check if that helps.

If the issue persists, you can try to reset the preferences of Photoshop manually using the steps mentioned here: https://adobe.ly/3dFRlyi

Please backup your settings prior to resetting the preferences. You can check: https://adobe.ly/2vNz6FG

Let us know how it goes!

Regards,

Nikunj

Does turning off »Use Graphics Processor« in the Performance Preferences (Photoshop > Preferences > Performance > Graphic Processor Settings) and restarting Photoshop have any bearing on the issue?
