I need to add text support in my qt opengl/qt3D application. I try to draw
text in a fbo like this:
sometimes it works, and sometimes not : black or crash in
drawCachedGlyphs ... depending on what I was doing before (for example
it don't works if I was previoulsy drawing a texture). I have tryed to
setup various opengl state, but I don't which one to setup to ensure
to have a clean opengl state to draw the text using opengl engine ?
