I don't understand what you're saying about the three different buffers and if you mean that there's a hidden buffer I don't see in xterm but which is used somewhere else in the stack.
I exclusively use bitmap fonts in terminals and editors for crisp and clear text and cannot get bitmap fonts to work in st config.h anymore.
