Addition: The Lines only appear with OpenGL 3x and above, 2x resolution looks fine

Another update: On 2x it now also appeared on some Torches. And a specific room in Dawn of Sorrow is also glitchy on OpenGL. On Software it looks like this, which is correct (the ghosts making the platform visible)

On OpenGL its always visible

And another issue I found, the Bat Company Boss on OpenGL looks like this, the pattern it has being entirely messed up

While its supposed to be an actual shape (the 2 screenshots dont show the same shape but every shape is messed up on OpenGL)

This is a known issue upstream. I will leave this issue open until it's fixed and integrated here, but in the meantime I encourage you to comment on that ticket if you haven't already.

And the last issue I think I noticed before I gave up on OpenGL was a totally fucked Death fight. Possibly there are more graphical glitches in the Abyss Area of Dawn of Sorrow, but this is what I noticed (posting this here as its my compilation of issues if the melonDS Devs ever look at this issue as I linked to it there)
