Unfortunately, this problem occurs when nothing is being written to the screen. Well, nothing except the mouse cursor image as it's being moved around which is why I thought the problem was with the mouse functions. However, I later discovered that the problem occurred when simply blitting from the screen with the mouse not even installed. After beating my brains out over this day after day, I've decided (right or wrong) that it's a buggy VESA bios implementation and have emailed the manufacturer in hope of getting a fix but I don't think it's going to happen. I wish blasting this program with two barrels was a real option, but I've worked on it too long so I guess I'll just have to find some way to work around this thing.
