How to Fix Filmora Wondershare BugSplat Error?

The BugSplat error in Filmora Wondershare is a low-level crash that usually appears during launching or rendering. This error is most often triggered by outdated or incompatible graphics drivers or Filmora’s reliance on D3D11 hardware acceleration. If your system does not fully support D3D11, or if the GPU drivers behave unpredictably, Filmora may crash and report a BugSplat error.

Other possible causes include corrupted BugSplat registry entries, enabled hardware acceleration on weak or integrated GPUs, or leftover cache files. When Filmora offloads rendering tasks to underpowered hardware, stability issues can occur and lead to repeated crashes. Below are the most effective solutions to resolve this error.

1. Update GPU Graphics Drivers

Updating your graphics drivers ensures compatibility between Filmora and your GPU. Outdated drivers are one of the most common causes of rendering crashes. Installing the latest drivers often fixes DirectX conflicts and improves stability.

1. Press Windows + R, type dxdiag, and press Enter.
2. Go to the Display tab and note your GPU manufacturer (e.g., NVIDIA, AMD, Intel).
3. Visit the official website of your GPU vendor, enter your GPU details, and download the latest driver.
4. If available, choose Clean installation to remove corrupted files and old configurations.
5. Restart your computer and relaunch Filmora to test stability.

2. Edit runtime_config.xml to Disable D3D11 / Adjust PreferDevices

Filmora relies on D3D11 by default, but some systems experience instability with this API. Modifying runtime_config.xml allows you to disable D3D11 and force Filmora to use an alternative rendering path.

1. Close Filmora completely.
2. Navigate to:

   C:\Users\<YourUsername>\Documents\Wondershare Filmora\config\

3. Create a backup copy of runtime_config.xml before editing.
4. Right-click runtime_config.xml → Open with > Notepad.
5. Add or edit the following line:

   <EnableD3D11>false</EnableD3D11>

   

6. Save changes (Ctrl + S) and close the editor.
7. Restart Filmora and check if the error persists.

3. Delete the BugSplat Registry Key

BugSplat collects crash reports, but corrupted entries can repeatedly trigger errors. Deleting this registry key often resolves the issue.

1. Press Windows + R, type regedit, and press Enter.
2. In Registry Editor, first create a backup via File > Export.
3. Navigate to:

   HKEY_CURRENT_USER\Software\BugSplat\

4. Right-click the BugSplat folder → Delete → Confirm.
5. Restart your PC and launch Filmora.

4. Disable Hardware Acceleration

Hardware acceleration shifts processing from CPU to GPU. While it boosts performance, it may also cause instability if your GPU is weak or drivers are unstable. Switching this setting can often stop the BugSplat error.

1. Open Filmora → File → Preferences.
2. Go to the Performance tab.
3. Toggle Enable Hardware Acceleration for video rendering and playback (disable if enabled, or enable if already disabled).
4. Click OK → Restart Filmora.

5. Reinstall Filmora Wondershare

If none of the above methods work, reinstalling Filmora ensures that all corrupted or misconfigured files are replaced with fresh copies.

1. Press Windows + R, type appwiz.cpl, and press Enter.
2. Locate Filmora Wondershare, right-click, and select Uninstall.
3. Download the latest installer from the official Filmora page.
4. Install Filmora and restart your PC.
