I have no issues with Direct3D 9.
I can confirm that the latest VDub (test) also hangs with DirectX9, and the only way to fix it is to kill it from the task manager.
Switching to DirectX11 solves the problem.
The hang seems to always occur in one specific instance: when I switch from VDub to another program/window while a video is playing (+AVS loaded via CID as usual).
I don't know which version this has been happening since, as I was previously working with OpenGL.

I don't know if anyone will care, but:

With Display options set to Use OpenGL, scale at 75%, and filter as Bicubic, the image comes out somewhat aliased. I haven't seen it happen with any other combination yet.



Bicubic on left, bilinear on right.

Any kernel introduces some artifacts.

When zooming to see the REAL quality of a video or an applied filter, I prefer to use the least invasive kernel possible.

Otherwise, what you are watching are the filter artifacts, not the video itself.

Bicubic shouldn't introduce these artefacts. It looks fine under DirectX 9, for example, so there's something wrong somewhere under OpenGL.

Actually I think it's just not implemented and is reverting to Nearest Neighbour.
