thanks for reporting your issue, we will run some tests on our end. In the meantime, you can try this and check if it improves the situation:
- disabling the OpenGL rendering from ScalerSettings (Manage Default Preferences with ScalerSettings)
- disabling the Audio Detection from the top section of Scaler (Clicking on the “Audio” button below the Midi Panic)
Remember to check if there is any update of Digital Performer available as well.
Cheers,
Ed
