Geysers appear to have difficulty rendering visibly through transparent blocks, particularly water. The issue is especially noticeable when viewing them through the uppermost layer of a water source.
In the attached screenshot, several geysers are located at the base of a waterfall. The water source blocks are positioned one block below the tops of the geysers, and the water flows down one additional block. The screenshot is taken from a slightly upward angle, looking through the water toward the geysers.
Despite the water being transparent, the geysers are barely visible or appear to be obscured entirely. This seems to indicate a potential rendering or transparency issue when geysers are viewed through water blocks.
