Comment (by malaawar):

 For my specific use case I need it to record just the target app,
 recording the full screen and cropping won't do for my use case
 unfortunately. There were no issues recording that same target app on 4/6
 of the machines i tested this on.

 Replying to [comment:3 MasterQuestionable]:
 > ͏    Maybe the target app could reject the display hook?
 > ͏    (try recording the full screen with crop in such case)
