The Castlevania games, texture ripping on upscale graphics
I don't know if this is in the scope of the project or not
In Castlevania: Order of Ecclesia I experienced a glitch where the background textures have vertical tears as depicted in the image, happens in all areas of the game.
It only happens with openGL x3 to x10 resolution, does not happen on openGL x1 or x2 resolution and does not happen on software (prolly because its at x1 resolution)
Happens both with and without improved polygon slitting, and happens both with and without JIT recompile
also tested in Castlevania: Portrait of Ruin and Castlevania: Dawn of Sorrow, happens in both those games under the same conditions

probably just inaccuries piling up until they make an integer difference.
so that would be the kind of thing that the emulator eventually aims to fix at some point or no?
I was refered to here from the MelonDSDS Developer about my findings about this issue in Dawn of Sorrow, https://github.com/JesseTG/melonds-ds/issues/170 is my thread of all the issues I was able to find during my playthrough of Dawn of Sorrow, it might be useful having more examples
