No, no plans. And in fact, the complete set of direct Xlib text drawing
functions will be semi-deprecated in GTK+-2.0 in favor of Pango-based
functions.

My guess is that something else is drawing the background of the
window, or, maybe it just flickers.

The way to avoid flicker, much more comprehensively, is to use 
double-buffering, and GTK+-2.0 makes this trivial.
