Original implementation initializes a ridiculously wide buffer where item graphics and names are then copied to and is then shown in parts depending on what items should be visible in item tab. When item counts go over ~32k in x-direction in pixel coordinates, the very low level drawing functions int16 variables overflow and item graphics are then drawn over each other.
It's now changed to blit item graphics and names by on demand depending on the item indices, which does not require a huge buffer and works regardless of the amount of items, since only 11 are visible at any one time and the x-coordinate stays well within INT16 limits
