What's the problem? Describe what went wrong.
Possibly a minor texture issue that manifests as a light-gray polygon on the corners of the character's eyelids during most in-engine cutscenes while he blinks. Appears to be a misrepresentation of a preexisting, subtler texture.
What steps will reproduce the problem?
Via Story or Library, anomaly can be seen in cinematics before stages Prison Island, Sky Troops, Lethal Highway and Cosmic Fall. Also visible in Westopolis' three endings, though not in the cutscene immediately before Glyphic Canyon.
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
5.0-9132
Is the issue present in the latest stable version?
Yes, 5.0
If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

Looks like some kind of blending issue - does the issue happen in the software renderer (I recommend using a savestate at the exact moment and loading it in the software renderer.)

The fifolog would probably be useful here as well.

Here. The "problem" object appears to be number 37.

Seems related to: https://bugs.dolphin-emu.org/issues/10346
Maybe worth trying a pre tev-fixes build to confirm that.

Still occurred in 4.0-1146 with all default settings. The issue linked above implies that TEV Fixes New was implemented in 4.0-1192, right?

There is a residual issue when using D3D11/D3D12 with ubershaders, but this can be avoided by not using ubershaders (or using hybrid ubershaders) or by using a different backend: #12609

I object to calling this fixed, the rendered result is still different when comparing the hardware render and the Dolphin render side-by-side. Yes, it's no longer obviously wrong, but something is still clearly different with the lighting/normal calculation.
Updated by pokechu22 over 3 years ago
I suspect that the difference is just Dolphin handling rasterization differently, but I can probably test by hex-editing the fifolog to use 1 instead of NaN and seeing if it renders the same way on console (and in Dolphin).

I'll mark this as work-started but leaved the fixed in set for now until we get a definitive response.
I think the big motivation to merging it was to see if we could get some more cases.

There is indeed still a difference which doesn't happen on console if the fifolog is hex-edited to use 1 instead of NaN: https://github.com/dolphin-emu/dolphin/pull/9928#issuecomment-893043811
Updated by JMC4789 over 3 years ago
Is it related to the NaN issue though? It doesn't seem to be.
Updated by pokechu22 over 3 years ago
Yes, as the different offset happens when the coordinate is NaN (and not when it is 1). It's different from the solid color behavior, but it's still an issue related to handling of NaN.
