I also have the same problem as you, and would like to know have you know how to fix it yet. If yes could you share it here or how to solve this problem cause it annoys me a lot. Thank you!

Hi,

This issue of white jagged edges or "broken pixels" around transparent PNGs in CapCut usually points to how the software is interpreting or rendering the transparency (alpha channel) information.

Since you've confirmed the original PNG files are fine and this is a new issue in CapCut PC, let us try troubleshooting the potential causes within CapCut:

1. Restart Everything:

   • Close CapCut completely.
   • Restart your PC.
   • Reopen CapCut and try importing the PNG again. Sometimes a simple restart clears temporary glitches.

2. Check for CapCut Updates:

   • Ensure you are using the latest version of CapCut PC. Developers often release updates to fix bugs. Go to CapCut's settings or menu to check for updates. If an update introduced the bug, sometimes rolling back might be an option, but usually updating is the first step.

3. Clear CapCut Cache: Corrupted cache files can cause all sorts of weird visual artifacts and performance issues.

   • Go to CapCut PC's Settings (usually via the gear icon on the main project selection screen or within a project).
   • Look for an option related to Cache or Temporary Files.
   • There should be an option to Clear Cache. Click it and confirm.
   • Restart CapCut after clearing the cache and test the PNG import again.

4. Check Performance/Rendering Settings:

   • Go back into CapCut's Settings.
   • Look for Performance or Rendering tabs.
   • Hardware Acceleration: Try toggling hardware acceleration (GPU acceleration for rendering/decoding) settings ON or OFF. Sometimes, driver incompatibilities can cause rendering issues like this. Apply the change, restart CapCut, and test. Try both states (enabled and disabled).
   • Render Quality/Proxy Settings: While less likely to cause edge artifacts, check if any preview quality or proxy settings might be affecting how images are displayed. Try setting preview quality higher if possible.

5. Test Different PNGs:

   • Try importing a different transparent PNG that you haven't used before.
   • Create a very simple test PNG (e.g., a circle with a transparent background) in an image editor and try importing that. This helps determine if the issue is specific to certain PNGs or affects all transparent imports.

6. Re-export the PNG:

   • Open the problematic PNG in an image editor (like GIMP, Photoshop, Photopea online, etc.).
   • Re-save or re-export it as a PNG-24 (which includes full alpha transparency). Make sure any options like "interlacing" are turned off. Ensure transparency is explicitly enabled during export.
   • Try importing this newly saved version into CapCut.

7. Check Project Settings: Ensure your CapCut project settings (resolution, frame rate) haven't been changed in a way that might conflict, although this is less likely to cause pixelated edges specifically on PNGs. Ensure that your project's background is set to transparent or matches the desired output. Sometimes, a non-transparent project background can cause visual artifacts around transparent images.

8. Verify Image Integrity: Open the PNG file in another image viewer or editor to confirm that the transparent background is intact and there are no unintended artifacts.

9. Reinstall CapCut: If none of the above work, the CapCut installation itself might have become corrupted.

   • Important: Back up any important CapCut projects first if they aren't stored in the cloud.
   • Uninstall CapCut PC completely.
   • Restart your computer.
   • Download the latest version from the official source and reinstall it.

10. Use CapCut's Background Removal Feature: If the issue persists, consider using CapCut's built-in background removal tool to eliminate any unwanted artifacts:​

    • Import your image into CapCut.​

    • Select the image in the timeline.​

    • Navigate to the 'Cutout' option in the top right panel.

    • Enable 'Auto Cutout' to remove the background.​

11. Consider Graphics Drivers: Although the issue is within CapCut, sometimes outdated or corrupted graphics card drivers can interfere with how software renders visuals, especially transparency. Check the manufacturer's website (NVIDIA, AMD, Intel) for the latest drivers for your specific graphics card.

If you've tried all these steps and the problem persists, it's highly likely a bug introduced in a recent CapCut update. In this case, the best course of action is to report the bug directly to CapCut technical support by writing an email to [email protected], providing details about your CapCut version, operating system, and ideally, a sample PNG that causes the issue.

By following these steps, you should be able to resolve the issue of broken white pixels appearing around your PNG images with transparent backgrounds in CapCut PC.
