[D3D9] Screen shaking during FMV in all Hatsune Miku games

[Leopard20]

The screen shakes when playing the intro videos.

I'm not sure when this started happening, but I'm running the latest dev build (v1.10.3-550)

I'm not sure if this is related or not:
#13370

[hrydgard]

#13370 is likely related yes. The new framebuffer management that helped fix Test Drive needs a bit more work.

[hrydgard]

Is this ok now after #13397 ?

[Leopard20]

Nope. Not fixed yet.
Not sure if this is useful (it appears to be empty):

This only happens in D3D9, right?

[Leopard20]

I'm on Android! ¯_(ツ)_/¯
Vulkan and OpenGL

[hrydgard]

Oh! Weird.

Using postprocessing effects?

[Leopard20]

Good guess! Yeah. I removed the PP effects and it now looks fine.
I think both of "natural colors" effects have this issue. The rest looked fine.

I'll see if I can find the issue.

I'm guessing the game somehow ends up drawing the video in two different ways, one frame directly to the backbuffer and the other through a framebuffer, and it flips between those and there's a subtle offset bug in one of them when using postprocessing ...

[Leopard20]

You were right about D3D9 though. It is broken with or without the shader. So please add the tag again.
I fixed the issue with one of the shaders. I'm not sure what the blurry one is doing tbh! :)

Yes, as per #3417. Maybe this is related to DrawFramebufferToOutput when it goes directly through presentation, i.e. not accounting for the half pixel offset?

Yes, that's what I'd guess.
