Running a MacPro5,1 with a VEGA 64 and Catalina 10.15.6 with OpenCore 0.5.9 and the most recent Lilu + WhateverGreen. When trying to capture video for some programs I get an error with video encoding. The following is one such error:

Code:
failed: Error Domain=AVFoundationErrorDomain Code=-11844 "Cannot Capture" UserInfo={NSLocalizedDescription=Cannot Capture, NSUnderlyingError=0x600000dc5da0 {Error Domain=NSOSStatusErrorDomain Code=-67394 "(null)"}, AVErrorRecordingSuccessfullyFinishedKey=false, NSLocalizedFailureReason=There was an unexpected problem with the graphics sub-system that prevented screen capture.}

I have allowed screen recording in Security& Privacy/Privacy. The app developer swears up and down that this is a hardware compatibility issue, so I have to believe it has something to do with a setting in OpenCore.

It's been suggested that perhaps I should try using an iMacPro1,1 for the SMBIOS setting, but I'm not sure what all settings I might want to try. Here are my current settings:
