PCSX2
[BUG]: Graphics that are forced to be without bilinear filtering on SW mode are distorted
Describe the Bug
While playing the PAL version of Fire Heroes, some UI elements seem to have both horizontal and diagonal distortions, almost like the quads that contain those UI pieces have the diagonal side moving around a bit.
This graphical glitch does not happen in any of the existing hardware modes (checked on DirectX; OpenGL and Vulkan), only on Software mode.
Reproduction Steps
- Start a new game or load a save file while playing in Software Mode, then proceed into an episode.
- As soon as you are ingame (within a cutscene as well), press START to pause the game.
- Go into one of the available menus: there's distortion in the Tower Map, Status and Victim List menus.
Expected Behavior
The UI elements should be clean of distortions.

Logs & Dumps
So... Breaking news: I was testing some final changes I was doing to a fantranslation project of Persona 3 FES, both for the PAL and the NTSC-U versions, and it seems that during the Erebus fight, at the end of The Answer (though this seems to happen a few times, usually on boss fights), whenever the battle UI (on the right) is displayed and you are not in control, the PC/NPC HP/SP values are distorted as well.
Reproduction Steps
- Play in software mode. Hardware mode seems to force bilinear filtering, clearing out the issue.
- Load a game and go fight a boss. I've seen this while fighting Erebus (the final boss) of The Answer.
- See the UI on the right side of the screen whenever you are not in control of the scene (a.k.a.: whenever the left UI elements are hidden, except the RUSH indicator).
The settings are the same as those used on Fire Heroes, though I did a quick test on 1.6.0, DirectX Software, and the error persists. This might be a global error and not one localized into a single game.
Issue happening on PAL version (since the UI is generally stretched out by the game, it looks worse):
Issue happening on the NTSC-U version:

Just to note both are double wrong. Firstly the distortion, but secondly it's supposed to be nearest drawn, not bilinear.
Sorry, I was not informative enough: I only tested Fire Heroes, and in software mode.
That is on hardware mode, correct? The UI already displayed properly on hardware mode.
So I got good news and bad news. Good news: software mode now seems to render the UI correctly:
Bad news: now Vulkan shows vertical lines. Much less obvious, in fact.
Tested again today with v1.7.5912. No changes since the last update, the distortion on the Tower Map and the Episode texts on the Victim List are still present.
