add:
o.show_overlay = False

to your .axisrc file.

It's a hidden file in your home directory (or add it if it's not there)

It does in my test machine (master branch) what branch are you using?
Yes in the file lib/python/rs274/glcannon

look for :

self.show_overlay = True

change to False

this is the glcanon.py file I have
paste.debian.net/1075513

I can't find " self.show_overlay" in it.

I was also tried to play with the colors of the overlays (0.00 to 1.00 values) in the color section (start at line 323) but it did nothing

ok you must be using linuxcnc 2.7.x....

remove these lines from glcanon.py:
        glDepthFunc(GL_ALWAYS)
        glDepthMask(GL_FALSE)
        glEnable(GL_BLEND)
        glBlendFunc(GL_ONE, GL_CONSTANT_ALPHA)
        glColor3f(*self.colors['overlay_background'])
        glBlendColor(0,0,0,1-self.colors['overlay_alpha'])
        glBegin(GL_QUADS)
        glVertex3f(0, ypos, 1)
        glVertex3f(0, ypos - 8 - linespace*len(posstrs), 1)
        glVertex3f(pixel_width+42, ypos - 8 - linespace*len(posstrs), 1)
        glVertex3f(pixel_width+42, ypos, 1)
        glEnd()
        glDisable(GL_BLEND)

sorry, still not perfect, the homing marks are now gone as well.:blink:

Edit:

instead of removing all the lines, just comment those lines:
now i have the homing marks, and no rectangle!!B)
        glDepthFunc(GL_ALWAYS)
        glDepthMask(GL_FALSE)
        glEnable(GL_BLEND)
        glBlendFunc(GL_ONE, GL_CONSTANT_ALPHA)
        glColor3f(*self.colors['overlay_background'])
        glBlendColor(0,0,0,1-self.colors['overlay_alpha'])
#        glBegin(GL_QUADS)
#        glVertex3f(0, ypos, 1)
#        glVertex3f(0, ypos - 8 - linespace*len(posstrs), 1)
#        glVertex3f(pixel_width+42, ypos - 8 - linespace*len(posstrs), 1)
#        glVertex3f(pixel_width+42, ypos, 1)
#        glEnd()
        glDisable(GL_BLEND)

I wish it was a way to control the size of them and the color, maybe even the font and put classic 7 segment dro font, and make them a bit larger then the small font, also bright yellow on the black background will be very easy to read.

Glad you got there.
I'm sure you could change those things - just the effort is quite high.
The color shouldn't be that bad to change.
lib/python/hershey defines the text in openGL.
