Hey, @18505892. Welcome to the Lightroom Community. Your post has been moved to Lightroom Classic. I'll help you figure this out. Please share the system info from Lightroom from Help > System info > Copy and paste into a text document > Upload and attach here.
Have you recently updated the OS? Does this happen after you've applied specific edits to the image?
As primary steps, try this:
- Unplug additional displays & use only one by default.
- While holding down the ALT + SHIFT keys, launch Lightroom from the Creative Cloud desktop app. Select 'Yes' when prompted to reset Preferences.
- Go to Edit > Preferences > Performance > Use Graphics Processor > Set it off if it is on Custom or Auto. If this shows any differences, please check this article to troubleshoot further: https://adobe.ly/3uYiJo4
Let me know how it goes. Thanks!
