Hopefully this information is helpful.
I played on the lowest resolution and framerate(30) possible ingame and use intel uhd 620 intergrated graphics on a i7 cpu i believe. Not sure when it was made but it is pretty old. Im pretty sure the bug occured due to my computer having old hardware and no dedicated gpu, although it can run games like Undertale and Tf2 run pretty good. The game was also launched from the itch desktop app but I'm not sure if that matters much.
