Does this happen if all graphical enhancements are disabled? (In particular the internal resolution and anti-aliasing)

The lines are definitely faded but still there: https://i.imgur.com/IFKq7MF.png & https://i.imgur.com/6gFdpm9.png

I'm pretty sure this is how the game works. Dots seem to be present on a video from real hardware, and using the hardware fifoplayer I was able to reproduce the same lines with the fifolog you attached.

Looking into it briefly, it seems like the game's text-drawing code probably has an off-by-1 error and it's cutting into the next character (for instance, "i" picks up a bit of "j" near the bottom, and "o" picks up the entirety of the left side of "p"). It's not always visible because the text isn't rendered at a 1:1 size with the font, meaning the broken row of pixels may not be shown, so at native IR it's mostly invisible, but at higher IRs it becomes more visible. Manual Texture Sampling does not affect it.

Is there any way for me to fix this on my end?

It might be possible to fix it using texture dumping and dolphin's custom texture functionality (i.e. editing the font so that the issue doesn't happen), but I don't know exactly how you'd do it.

Can we re-look into this? looking at the latest blog (https://dolphin-emu.org/blog/2023/02/12/dolphin-progress-report-december-2022-january-2023/)

Just checked this now, looks like it's fixed! Can this be updated to fixed? Although you an see small lines, should I make another bug report? https://i.imgur.com/nh37u6q.png

I don't think anything's changed that should have fixed it (apart from maybe you switching to a different GPU or changing the internal resolution or vertex rounding settings).

The small lines are behavior on real hardware based on my previous testing.

is there no way to fix those lines? even ifd they are on real hardware?

Try graphics -> enhancements -> texture filtering to "force nearest". This should fix the lines, but it'll also make all textures look pixelated.

It'd probably be possible to make a game patch or graphics mod to fix it for only the text, but I don't own the game so I can't help with that.

"Nearest" refers to nearest neighbor scaling, which naturally creates the pixelated effect. The other option is bilinear scaling, which smoothly interpolates nearby pixels on both the x and y axes, blurring things slightly (and in this case, grabbing pixels from neighboring letters, which produces those lines). With how the game is made, you'll need to choose between one of those two results.

Alright, ty!
