4:3 cropped image screenshot bug

[Lotesdelere]

When playing back an old Hercule Poirot episode which was filmed in 4:3 resolution I crop the image for removing the black bars on left and right sides:

The image itself is 768x576. (There is no window left border because I align the side of the image to the side of my screen)

But if I take a screenshot using Shift+S then the resulting 768x576 image is taken from the non visible left black bar so the final image is missing the right part:

I cannot reproduce the issue. Works fine with 16:9 video cropped to 4:3. Shift+S snapshot is centred properly.
Only Poirot can solve this mystery

I've tried the same thing with a 16:9 video cropped to 4:3 and I got exactly the same result:

Yep. Same thing here.

The only workaround would be to use the Windows Snipping Tool I guess.

Hmm, then Poirot would check conditions (vlc settings, media format). Win32, Vout: Automatic (=> Direct3D9 video output), Hardware decoding: Automatic (=> probably no or dxva2), also default snapshot settings (png) here.

Same result for me whatever video output module is used.
However it's working fine when hardware acceleration is turned off.

Then it is a known problem. Video filters do not work with hardware acceleration, don't they? Or is it just a bug in the video snapshot feature? I do not know.

[Lotesdelere]

Well, the image size is correct so some filter is being used but not centered.

The preview is correct:





But not the final file:
