Tekken Tag Tournament HD (NPEA00326): Corrupt polygons at certain points

[Silanda]

Quick summary

Erroneous flat polygons appear at certain points on certain stages and, handily for testing, are front and centre during the first demo after the intro.

AFAIK they only appear when using the Vulkan backend. However, OpenGL has its own issues which make using that not desirable (see the clouds during the same demo)

EDIT: I've uploaded a second screenshot and RSX capture, though the capture seems to produce corrupt output when loaded.

Details

As above. Large, flat, polygons appear on screen. During the first demo they appear dead centre of the screen, but they also appear on certain stages at certain angles (e.g. on Eddy Gordo's stage, IIRC).

Tested using a variety of settings to no avail. The problem is present at default settings.

It's a graphics issue that has been around for a long time and hasn't been fixed.
I hope it gets fixed

Can reproduce this on the NA version of the game too [NPUB30590]. Steps to reproduce are boot game, press Start to skip the 'Namco presents' intro movie, then leave it for 5 seconds at the main menu for the first demo to start playing.

Graphic settings (WCB+RCB+WDB+RDB+SRM) have no effect. Accurate XFloat, plus the accuracy options in the Advanced tab have no effect. Issue is present both with LLVM recompiler and the static intepreter.

This may be an Nvidia driver specific issue. I have the same problem on my computer with an RTX 4070 Ti, but on my other computer with an RX 7900 XT these issues don't appear at all.
