The bug
When moving around and looking from different angles a stained glass pane which is located inside a water block, it looks weird and glitches . This doesn't happen with regular glass pane.
In the included gif you can see a block from a slightly different angle.

Still happening. With glass panes even with water block, the part of the pane slight above the surface of the water will glitch to where there water will disappear and all you will see is the block(s) through the water as if there is no water present.
