Black tank splash shield problem
I assume it's a splash shield anyway. When we flush our toilet in the motorhome (Thetford Aqua Magic V) things go on down for the first day or two of a trip. Then paper and stuff starts to build up...

Some toilets have a 45 degree bend in the drop pipe, I wonder if that is what you are seeing. As far as filling the bowl for a flush, that doesn't really apply for just pee. Although if there is toilet paper in the bowl you will need extra water to make sure it clears the bend in the pipe.
