[BUG]: Dark Cloud 2 (SCUS-97213): HUD visual glitch (texture sampling?)

[trostboot]

Describe the Bug

There is some additional garbage on the lower right corner below the health bar portion of the HUD. Possibly a texture sampling issue, possibly related to #4440, although unlike that issue this one is present across all renderers (incl. the wip vulkan branch).

If resolution is set to a non-native multiplier on a HW renderer, and the Wild Arms hack is enabled, the issue is fixed. The issue stays fixed even if resolution is set back to native, as long as the HW hacks toggle is still enabled, even though the Wild Arms hack is greyed due to native resolution.

Verified to not be an issue on real hardware.

Reproduction Steps

Load game, enter any dungeon area, move eye focus to upper left of screen.

Expected Behavior

Clean HUD with sweet sweet transparency.

Can confirm the graphical upscale bug in question on my side as well. Also, nice finding that hack discrepancy.

I'm not 100% sure if these extra few pixels were present at all a short while back, it's minor enough I might have glanced past it and ignored it. I'll jump back some versions to test and return.

EDIT: Been present since 1.6 at least so I've just been blind/ignoring it.

how is this on latest nightly

[coornio]

It's still there, except now it occurs in software as well.

[refractionpcsx2]

It always occurred in software too. I know why it happens, but I need to do some tests on hardware to how it should be handled.

the game samples past the width of the texture (in page width, rather than texture size), which does weird stuff on real hardware and happens to not display the pixels from the next row in the texture, like here, but need to investigate further.

I have a bodge fix for this in #6553
