ugh, It might just be the onboard Intel HD 530, the way it displays...(I see thats its a DirectX 12 chip, not much experience with that)
Are you using the Beta Drivers for it or Standard release?
You should have 1.28e installed out of the \Program Files folder and placed someplace else. Without the compatibility mode nor the admin setting.
Are you running in D3D or Glide(with nGlide)?
MrJelly at the SimHQ recently updated the main exe of the EAw version your using with some fixes plus Glide 3 support. You might want to contact him here or over there.
