HDR Flip Non Video Area is grey

[vdrfan]

with Flip and HDR enabled - non video Area is not 100 Percent Black.
you only can see the difference in attached image with OLED and HDR enabled.

when you Pick Color (at Top/Bottom of Image) then you will see RGB (2,4,1) instead of (0,0,0).
This does not happen when using swap discard.

I don't know, maybe driver's issue.

[vdrfan]

you are right - it is a driver issue, with newer AMD driver there is no grey-problem with MPCVR.

other qeuestion - maybe you know that problem.
Setup: Radeon Ryzen 3400G - with Vega Graphics.
with most AMD drivers i have problems with some 720p h264 Videos (50p video stuttering and showing only 15-30 frames/sec).
the stuttering is with EVR, MAD, and MPCVR - and it is only with Hardware Decoding.
some Drivers work correct with these 720p Videos - but these drivers have the grey bug ...

thanks for your work, regards, onur

Stutter issue sounds like same as this one:
Nevcairiel/LAVFilters#496

I suggest reporting it to AMD.
