Hi, I'm quite new to OpenGL.
I have written an application that makes a geographic mapping in c# using openTK opengl.
It works quite well and now it became necessary to add text on my screen for some labels.
I used quickfont library. added it as subproject and reference, added the font folder to my project.
what happens now is that whenever I try to load a font, all my screen goes black. My other drawings dissapear.
I'm not even using a print method to put anything on my screen.
the font seems to load ok, as I get a pointer and the data seems to be filled in.
I tried with loading various different fonts and always get the same result, my screen goes black. removing the font declaration and all comes back
this is what I add
controlsText = new QFont("Fonts/HappySans.ttf", 16);
controlsText being declared earlier in the members as QFont.
Does somebody have an idea in what direction I have to search why the drawing goes blank ?
pictures show before and after
thanks in advance,
