Does running Single Core avoid the issue?

yes and no

i still get the same error, but in single core i can press ignore and the game will works, while in dual core, if i press ignore, dolphin freezes and crashes

Please record a 3 frame fifolog after pressing ignore on the screen that throws the errors. That should let us see the issue.

If you selected "ignore for this session" and then selected Emulation → Reset, that doesn't reset the panic alert state (since the reset button in the UI just tells the game that the console's reset button was pressed, and it's up to the game to decide what to do with that information, same as with the reset button in the HOME Based nmenu). If you have the MASTER log type enabled and set the verbosity to error, warning, or info, you should still see a lot of spam for the same panic alert.

Based on that fifolog, it seems like this error is coming from the reflections in the IV drip bag on the main menu (object 432 on the first frame); the errors stop if I set the object range to 0-431. And, yes, the game is rendering that main menu (as well as a loading screen and the title screen) behind that connect the classic controller message. See these images, and it's rendering that IV drip bag even though it's outside of the camera frustum.

There's also an issue where the fifo recorder doesn't properly save all of the data related to the binormal and tangent vectors (which are used in reflections). PR 10676 fixes that. This only affects the fifo recorder, so it wouldn't cause the panic alert during normal gameplay, but it does make debugging it/checking that things are working properly more difficult.

Can you record a new fifolog using that pull request where the IV drip bag is on screen (maybe two, one on the main menu and one at the start of the campaign where hopefully it's not blurred the same way)? That way I can test it on real hardware more easily.

is there an artifact for that?

There's a Windows one at https://dl.dolphin-emu.org/prs/87/12/pr-10676-dolphin-latest-x64.7z but I don't think we ship linux artifacts unless something recently changed and I missed it; you can build from the source here though.

To clarify, the thing I'm looking for is a fifolog of this scene where the reflective surface is visible using the PR build. (Looking at that video, I'm guessing that it's only visible/easy to see in that cutscene and not on the main menu.) I think this is an in-engine cutscene (it definitely seems to be one on the main menu). The easiest way to do this would be to pause the game at the right time with F10, start recording the fifolog, and then resume the game.

Thanks. Frame 15 or so of codcamf seems to be usable for more investigation on my end. I'll look into this more later. (The binormal vectors do seem to still contain garbage data, but it looks like the game only uses the normal and tangent vector, so my pull request seems to be working correctly.)
