Interlaced frame type mismatch

Hi Toni,

Still enjoying the hell out of WinUAE, as always

There still an issue which I hope you can fix. We talked about it in 3.4.0. series, but unfortunately never got solved.

It's about the Interlaced frame type mismatch behaviour in real interlaced modes. Please see attached log from testing on Windows 10 x64 Creators update. It does the following:

Code:
51-733 [3468 000-000]: Interlaced frame type mismatch 1<>0 (-1,616)
51-854 [3474 000-000]: Interlaced frame type mismatch 1<>0 (-1,-1)
51-953 [3478 000-000]: Interlaced frame type mismatch 1<>0 (-1,617)
52-074 [3484 000-000]: Interlaced frame type mismatch 1<>0 (-1,-1)
52-173 [3488 000-000]: Interlaced frame type mismatch 1<>0 (-1,616)
52-294 [3494 000-000]: Interlaced frame type mismatch 1<>0 (-1,-1)
52-393 [3498 000-000]: Interlaced frame type mismatch 1<>0 (-1,617)
It seems the mismatch is alternating on the last and first line of every other field, which may be suggesting that both WinUAE -and- Windows or video driver are trying to match correct field?

The interlaced frame type mismatch happens on a series of video cards, tested in Windows 10 (both older and newer AMD and NVidia cards).

Other than that more testing seems to suggest that the issue starts occuring with WinUAE 3.4.0 beta 1, the first beta version with Wasapi pull mode.

Here is additionally the post from the 3.4.0 thread describing the same issue (dismiss the beta 5/6 comments, as current testing shows differently). It also holds a sample config for easy testing on LCD (I'm mostly using CRT):

As said there seems a (small?) chance that interlaced behaviour has changed in Windows 10 DirectX and/or video drivers, which guarantees correct field type behaviour already?

If that may be the case, could you possibly make a config option to disable the frame type matching in WinUAE?
