Plugin GUI Appearing as a Black Box - How to fix it

For the attention of Windows users only

If your Sonnox plugin simply shows an empty black box when inserted, it is likely to be a graphics card related issue, specifically with OpenGL, which some Sonnox plugins depend on in order to function and display the GUI. 

Summary of things to check - 

• Check that any dedicated GPUs are running the latest firmware

• Check that OpenGL drivers are fully up to date alongside latest GPU F/W

• Switch OpenGL off in plugin preferences if no change following the above

 Updating OpenGL Drivers

1. Open Device Manager.

2. Expand Display adapters and then right click the graphics driver to update driver. Here your display card may be AMD, Intel, or NVIDIA or any differently branded GPUs. 

3. Search automatically for the updated driver software.

Troubleshooting / Alternative Fixes

If updating GPU and OpenGL drivers do not resolve the problem, then in some cases, OpenGL can be disabled manually - 

• Go to Documents > Sonnox > Preferences

• Open the .xml file relevant to your Sonnox plugin 

• Change the line <VALUE name="UseOpenGLRenderer" val="1"/> to <VALUE name="UseOpenGLRenderer" val="0"/>

• Save the file

• Relaunch your DAW

• Please note, this workaround will not work for our Drum Gate or Claro plugins due to their dependency on OpenGL rendering.
