Hi
Welcome to Microsoft community.
The issue you're experiencing with Adobe Lightroom and Photoshop might be related to software or hardware compatibility, or it could be a bug in the Adobe application itself. Here are some steps you can try to resolve the issue:
1. Update Your Graphics Drivers
Ensure your AMD Radeon Vega Mobile graphics driver is up-to-date. You can download the latest drivers from AMD's official website: https://www.amd.com/en/support

Watch out for ads on the site that may advertise products frequently classified as PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it.
2. Update Adobe Software
Make sure both Adobe Lightroom and Photoshop are updated to their latest versions. You can do this through the Creative Cloud desktop app.
3. Change Performance Preferences
In Photoshop, go to Edit > Preferences > Performance and ensure that "Use Graphics Processor" is checked. If it's already checked, try unchecking it, restarting Photoshop, then rechecking it and restarting again.
In Lightroom, go to Edit > Preferences > Performance and check "Use Graphics Processor". If issues continue, uncheck this option.
4. Reset Preferences
Try resetting your preferences in both Adobe Lightroom and Photoshop:
- For Lightroom: Hold down Alt + Shift when starting Lightroom.
- For Photoshop: Hold down Alt + Control + Shift when starting Photoshop.
A dialog box will ask if you want to delete the settings file; select Yes.
Please let me know if you need any further assistance. Thank you.
