extracted games end up with weird diagonal lines across most in game visuals

[retardriot2017]

running amd cpu / gpu. arch linux. whenever i extract an RPGmaker game (whether on a win10 VM with shift-jis and proper JP region or arch itself) i get this strange diagonal corrupted line across specific visuals. example attached. the games run perfectly otherwise. you can see the diagonal across the brown character background as well. what's going on here? do AMD cpus have fucked up extraction instructions or something?

Are the base images themselves like that or only when displayed in RPGM?

i havent checked the images themselves, but checking the games again, they flicker from normal to diagonal now, so the core content is clearly there, it just isn't rendering properly.
