For the record, the black issue is now solved. Instead of creating, setting and then destroying the pens I just made one and then re-use it in all places where I set the colour. So far it works perfectly.
The OpenGL issue is still not solved, but I am running on an eee PC so it might be the low-end Intel card that is causing the problems. I've had issues with Ruby and OpenGL on other low-end...

I know what the black problem is now. It is leaking GDI objects and when there are no more it goes black. I've narrowed it down to the brush and the pen objects, if I comment out the call to make/set them then the GDI usage stays flat.
I have also tried storing the old pen and brush and destroying them after I have set the new ones, no effect.
Could this be a wx issue? There is this bug...

I'll try re-installing them when I get home, however I am a little skeptical this is the problem. I have no problems with OpenGL with any other apps or when using Java with JOGL (Java OpenGL bindings).
Note also that when I wrote: 'I have tried explicitely setting the pen and brush to white on the line before drawing (incase it was being lost/not set/overridden/etc), makes no difference.'...

I am trying to use wxErlang for graphics in a 2d game framework I am building.
My first problem is that when I call 'wxGLCanvas:new' it doesn't return. I've tried different parameters, using different wx Frames/Windows/Panels as it's parent, and I cannot seem to get this to work. The openGL samples also suffer from the same problem.
Next I switched to using the wxClientDC and wxBufferedDC...
