There's an issue that's really pissing me off.
A note behind a note I'm about to press for some reason gets hit instead of the note that's supposed to get hit.
This has been an issue I've had for a long time, but I'm just now realizing what's happening because it hadn't happened on a song with jacks yet, and I can clearly see what's going on now. Before I thought it was just a problem with my keyboard, but now I see that's not the case.
Doesn't happen all the time, but it does impede my gameplay and trying to perfect songs. Like I've been playing various songs for a while, and only now on my feeling like playing Roses (Pico Mix) today do I for some reason have the problem arise again. Maybe it's a problem with the pixel stuff or the shaders? I don't exactly know what causes it yet.
