I don't have VirtualDub installed. Can you create a small sample for me?

The PNG issue seems to be something different, I suspect a bug in LAV.

the png works fine with evr. lavfilter sends rgb24 to evr. madvr normally gets rgb48, but with forced rgb24 the error is still there, so i don't see the problem in lavfilter.

should i create a new bug and check this problem again?

No, I just found out that the problem was simply caused by madVR auto-detecting the primaries to be DCI-P3, due to the width of 4096 only be used by DCI, and furthermore my DCI primaries had an incorrect white point. I've now fixed the white point and disabled resolution based DCI auto-detection. But really, this got nothing to do with this bug report.

Attached an uncompressed v210 in avi sample (warning, it extracts to 1.4GB). Sometimes madVR shows diagonal lines like the attached screenshot, and other times it only shows a black screen.

Fixed in v0.87.5. But don't try to DXVA deinterlace your sample with and AMD GPU, or you'll get a bluescreen!! Seems that the AMD DXVA deinterlacer can't handle 4K content... #:-O
