When u use the default "beginRendering(int width, int height)" depth-test is implicitly disabled by TextRenderer. If u want to control depth-testing u have to use "beginRendering(int width, int height, boolean disableDepthTest)" and enable depth-testing explicitly.

edit: ... and btw when using the 2D mode of TextRenderer the text billboards all lie at 0.0 z. If u want to change the z value of ur text billboard u have to use draw3D().
