I have not checked your code, but perhaps you could try moving the glass
block upwards very slightly, to make sure there is not a coincident surface
at the bottom. This could cause the strange dots you see at the top.

But if there is no coincident surface down there, then I am just rambling
for no apparent reason. =P

I like your picture though, very neat. Only thing I could suggest is perhaps
to get the glyphs to stand out a bit more.
