粒子の項目でプレビューが不正確すぎる

Hi @宮田34560910gvnu 

Thanks for reporting this. To help us understand what’s causing the inaccurate particle/grain preview, could you please share a bit more information?

• App version number

• Windows version

• File type you’re editing (RAW/JPEG/HEIC, etc.)

• Whether this happens with all photos or only specific ones?

In the meantime, you can try these basic checks:

• Zoom to 100% or higher. Grain/particle effects are only accurately visible at 1:1 or above.
• Toggle GPU acceleration: Go to Preferences > Performance. Turn Use Graphics Processor off, restart Lightroom, and check the preview again.
• Reset Preferences (as a test): Hold Shift + Alt (Windows) or Shift + Option (macOS) while launching Lightroom and confirm reset.

If possible, please also share a short screen recording showing how the grain looks in the app versus the exported result. 

Looking forward to your response!

Regards,

Srishti
