If renderer is OpenGL then it's the source of that bug, because i have different OS, video card and drivers, and i'm getting exactly same bug.

Just ran win32 build in wine with D3D9 plugin and got normal shadow.

Upload a two-frame fifo log and a reference screenshot showing the same scene, please.

A forum user mentioned that it still occurs even after the GLSL OpenGL rewrite in 3.5-1064. https://forums.dolphin-emu.org/Thread-wii-kirby-s-return-to-dream-land?pid=285711#pid285711

Replacing the broken mediafire FIFO log download from comment 8.

Better fifo log which also shows the shadow in working backends:

Some hours of debugging later: This game renders with logicOp=Noop and DstAlpha=1 the alpha channel, but dstAlpha + logicOp isn't supported by OpenGL nor Direct3D.
But it's working on D3D11 because this backend doesn't have logicOp support implemented at all. It just use the same based on blending hack as the D3D9 backend. But as blending support dstAlpha, this hack also does.

For reference, it seems like the issue does not occur in the software renderer anymore when testing on revision c1ddeacc9d09.

Not surprisingly, it also does not happen on real hw.

has there been any progress on this? still have that bug and i wonder if its going to be fixed at some point ?
Updated by Stevoisiak about 10 years ago
Can confirm the issue does not happen when using the software renderer or Direct3D. Only OpenGL
Updated by degasus almost 10 years ago
@idan345 This issue is hard to fix. We could add a check if the logicOp is Noop and emulate this with color masking, but other games may still be broken because of this issue.
But good luck, at least on some mobile GPUs, there will be an extension to use custom blending. This would allow us to emulate this feature there. But bad luck, this feature isn't possible on current gen desktop GPUs at all.
