Higurashi no Naku Koro Ni Sui [BLJM61255]

I am loading only required libraries and besides the opening video flickering red 4-5 times a second, the game seems to run smoothly. I haven't seen any Japanese characters glitch out in the text box like OP and others have reported; however, I am getting black bars that show up on every other background and appear behind the text box and sprites (see first image), as well as on occasion black splotches partially or entirely covering up some sprites (see second image).




 Does anybody know how to fix these two issues, or if not, how one would go about trying to fixing them?
